Source/WTF:

Make initialization functions more independent so that they can run in different
order. WTF::initializeMainThread initializes WTF threading, so that neither WTF nor JSC theading need to be
initialized before. RunLoop::initializeMainRunLoop() requires main thread to be initialized in some
ports, so it initializes main thread too. WebKit1 always calls WTF::initializeMainThreadToProcessMainThread()
before RunLoop::initializeMainRunLoop() so there's no problem there. GC threads are initialized alwayas by the
main thread. The rules should be simpler now:

  - JSC::initializeThreading: should always be called when JSC is used.
  - WTF::initializeThreading: only needs to be explicitly called when JSC is not used and process doesn't
    initialize a main thread or main run loop.
  - WTF::initializeMainThread: only needs to be explicitly called if process initializes a main thread but not a
    main run loop.
  - WTF::initializeMainThreadToProcessMainThread(): should always be called in WebKit1 before
    RunLoop::initializeMainRunLoop().
  - RunLoop::initializeMainRunLoop(): to initialize the main run loop. The only requirement is JSC::initializeThreading()
    to be called before if JSC is used.

WebAssembly: clear out insignificant i32 bits when calling JavaScript
https://bugs.webkit.org/show_bug.cgi?id=166677

Reviewed by Keith Miller.

When WebAssembly calls JavaScript it needs to clear out the
insignificant bits of int32 values:

  +------------------- tag
  |  +---------------- insignificant
  |  |   +------------ 32-bit integer value
  |  |   |
  |--|---|-------|
0xffff0000ffffffff

At least some JavaScript code assumes that these bits are all
zero. In the wasm-to-wasm.js example we store a 64-bit value in an
object with lo / hi fields, each containing 32-bit integers. We
then load these back, and the baseline compiler fails its
comparison because it first checks the value are the same type
(yes, because the int32 tag is set in both), and then whether they
have the same value (no, because comparing the two registers
fails). We could argue that the baseline compiler is wrong for
performing a 64-bit comparison, but it doesn't really matter
because there's not much of a point in breaking that invariant for
WebAssembly's sake.

[Modern Media Controls] Scrubber stops moving while scrubbing on macOS
https://bugs.webkit.org/show_bug.cgi?id=168518
<rdar://problem/30577637>

Reviewed by Dean Jackson.

Source/WebCore:

As we start to scrub, controlValueWillStartChanging() is called on
ScrubberSupport and pauses the media if it's not already paused. This
causes the play/pause button to change icon and for layout() to be
called on MacOSInlineMediaControls. This in turns sets the .children
property on the .controlsBar and eventually yields a DOM manipulation
which re-inserts the scrubber's DOM hierarchy, causing stutters during
user interaction.

Our solution is to make the .children setter smarter about identifying
that the children list hasn't changed and that no DOM invalidation is
necessary.

Make sampling algorithm more stable and introduce an abstraction for sampled data
https://bugs.webkit.org/show_bug.cgi?id=168693

Reviewed by Chris Dumez.

Before this patch, TimeSeriesChart's resampling resulted in some points poping up and disappearing as
the width of a chart is changed. e.g. when resizing the browser window. The bug was by caused by
the sample for a given width not always including all points for a smaller width so as the width is
expanded, some point may be dropped.

Fixed this by using a much simpler algorithm of always picking a point when the time interval between
the preceding point and the succeeding point is larger than the minimum space we allow for a given width.

Also introduced a new abstraction around the sample data: TimeSeriesView. A TimeSeriesView provides
a similar API to TimeSeries for a subset of the time series filtered by a time range a custom function.
This paves a way to adding the ability to select baseline, etc... on the chart status view.

TimeSeriesView can be in two modes:
Mode 1. The view represents a contiguous subrange of TimeSeries - In this mode, this._data references
        the underlying TimeSeries's _data directly, and we use _startingIndex to adjust index given to
        find the relative index. Finding the next point or the previous point of a given point is done
        via looking up the point's seriesIndex and doing a simple arithmetic. In general, an index is
        converted to the absolute index in the underlying TimeSeries's _data array.

Mode 2. The view represents a filtered non-contiguous subset of TimeSeries -  In this mode, this._data is
        its own array. Finding the next point or the previous point of a given point requires finding
        a sibling point in the underlying TimeSeries which is in this view. Since this may result in O(n)
        traversal and a hash lookup, we lazily build a map of each point to its position in _data instead.

* public/v3/components/chart-status-view.js:

Add biased coloring to Briggs and IRC
https://bugs.webkit.org/show_bug.cgi?id=168611

Reviewed by Filip Pizlo.

This patch implements biased coloring as proposed by Briggs. See section
5.3.3 of his thesis for more information: http://www.cs.utexas.edu/users/mckinley/380C/lecs/briggs-thesis-1992.pdf

The main idea of biased coloring is this:
We try to coalesce a move between u and v, but the conservative heuristic
fails. We don't want coalesce the move because we don't want to risk
creating an uncolorable graph. However, if the conservative heuristic fails,
it's not proof that the graph is uncolorable if the move were indeed coalesced.

If the UI process and web process for some reason end up using different versions of the WebKit framework, weird things happen
because the message format is different between versions. To avoid this, send along the WebKit bundle version from the UI process

[css-grid] Move the track sizing algorithm to its own class
https://bugs.webkit.org/show_bug.cgi?id=167988

Reviewed by Manuel Rego Casasnovas.

This is about moving the track sizing algorithm code out of RenderGrid to a new class
GridTrackSizingAlgorithm, making RenderGrid more compact and easy to maintain. A nice side
effect of this patch is the removal of the GridSizingData structure as it is no longer
needed. All the data structures in that class were transferred to GridTrackSizingAlgorithm
as private attribute members. The GridTrack class was also moved to the new file.

The algorithm execution starts with the call to run(). It's mandatory to call setup() before
any call to run() in order to properly configure the behaviour of the algorithm. You can
call setup() & run() multiple times for a single layout operation (normally twice, one for
columns and another one for rows). The algorithm uses a state machine to verify that the
client issues the calls in the proper order (i.e. first columns and then rows). After
finishing the layout, the client should call reset() to allow the algorithm to perform
cleanups and to prepare itself for another round of calls.

In order to implement the different behaviours of the algorithm depending on whether the
available size is definite or not, a strategy pattern was implemented in the
GridTrackSizingAlgorithmStrategy class. It has two subclasses, one for definite sizes and
another one for indefinite ones.

We took advantage of this change to perform some renames of the track sizing algorithm
methods that were still using the names from the first versions of the specs. Not only that,
the original track sizing algorithm method (computeUsedBreadthOfGridTracks) was split in 4
different parts representing the 4 steps of the algorithm.

No new tests as this is about moving code and refactoring.

Source/JavaScriptCore:

This patch optimizes accesses to module namespace objects.

1. Cache the resolutions for module namespace objects.

    When constructing the module namespace object, we already resolves all the exports.
    The module namespace object caches this result and leverage it in the later access in
    getOwnPropertySlot. This avoids resolving bindings through resolveExport.

2. Introduce ModuleNamespaceLoad IC.

    This patch adds new IC for module namespace objects. The mechanism is simple, getOwnPropertySlot
    tells us about module namespace object resolution. The IC first checks whether the given object
    is an expected module namespace object. If this check succeeds, we load the value from the module
    environment.

3. Introduce DFG/FTL optimization.

    After exploiting module namespace object accesses in (2), DFG can recognize this in ByteCodeParser.
    DFG will convert it to CheckCell with the namespace object and GetClosureVar from the cached environment.
    At that time, we have a chance to fold it to the constant.

This optimization improves the performance of accessing to module namespace objects.

NetworkProcess: Stop disabling buffering when NETWORK_CACHE is disabled in build

Reviewed by Alex Christensen.

It was added in r193752 as part of bug #137692 to fix an infinite loop in network process that happened in EFL
because they didn't enable the network cache at that time. I think that was actually a workaround, and it was
added without any comment so it has stayed there even when EFL enabled disk cache, and now that is gone. Looking
at current code I see no reason why buffering can't work with the disk cache disabled, so I think it's time to
remove that workaround.

https://bugs.webkit.org/show_bug.cgi?id=168570

Reviewed by Michael Catanzaro.

Source/WTF:

This has recently been added and the patch is good. It's just revealing a problem with our timers. The test is
posting a message recursively, and also starts a timeout timer to finish the test. The timeout timer is never
fired for us, because WebCore timers have lower priority than the one used by postMessage. ScriptExecutionContext
uses Document::postTask, that uses scheduleOnMainThread, that uses RunLoop::dispatch(). We are not setting any
priority for the timer used by RunLoop::dispatch, so it's using the default.
Use a RunLoop::Timer to schedule tasks to the main thread instead of using RunLoop::dispatch(). This allows us
to use a different priority, that is now set to G_PRIORITY_HIGH_IDLE + 20 to match WebCore timers. But it also
avoids the double queue we had with RunLoop::dispatch(), because scheduleOnMainThread() also queues the tasks.

Add the Briggs optimistic allocator to run on ARM64
https://bugs.webkit.org/show_bug.cgi?id=168454

Reviewed by Filip Pizlo.

Source/JavaScriptCore:

This patch adds the Briggs allocator to Air:
http://www.cs.utexas.edu/users/mckinley/380C/lecs/briggs-thesis-1992.pdf
It uses it by default on ARM64. I was measuring an 8-10% speedup
in the phase because of this. I also wasn't able to detect a slowdown
for generated code on ARM64. There are still a few things we can do
to speed things up even further. Moving the interference graph into
a BitVector was another 10-20% speedup. We should consider doing this
in a follow up patch. This is especially important now, since making
register allocation faster has a direct impact on startup time for
Wasm modules.

I abstracted away the common bits between Briggs and IRC, and moved
them into a common super class. In a follow up to this patch, I plan
on implementing biased coloring for both Briggs and IRC (this is
described in Briggs's thesis). I was able to detect a 1% slowdown
with Briggs on Octane for x86-64. This is because the register file
for x86-64 is smaller than ARM64. When I implemented biased coloring,
I was no longer able to detect this slowdown. I still think it's a
sensible plan to run Briggs on ARM64 and IRC on x86-64.

Source/WebCore:

After r207720, the following WebGL conformance tests started failing:
- /more/conformance/conformance/quickCheckAPI-S_V.html

We started throwing security errors in case where we did not before.
Chrome and Firefox are both passing these tests so our new behavior was not interoperable.

This patch reverts part of r207720 to restore our previous behavior.

Source/JavaScriptCore:

This turns the collector thread's workflow into a state machine, so that the mutator thread can
run it directly. This reduces the amount of synchronization we do with the collector thread, and
means that most apps will never start the collector thread. The collector thread will still start
when we need to finish collecting and we don't have heap access.

In this new world, "stopping the world" means relinquishing control of collection to the mutator.
This means tracking who is conducting collection. I use the GCConductor enum to say who is
conducting. It's either GCConductor::Mutator or GCConductor::Collector. I use the term "conn" to
refer to the concept of conducting (having the conn, relinquishing the conn, taking the conn).
So, stopping the world means giving the mutator the conn. Releasing heap access means giving the
collector the conn.

This meant bringing back the conservative scan of the calling thread. It turns out that this
scan was too slow to be called on each GC increment because apparently setjmp() now does system
calls. So, I wrote our own callee save register saving for the GC. Then I had doubts about
whether or not it was correct, so I also made it so that the GC only rarely asks for the register
state. I think we still want to use my register saving code instead of setjmp because setjmp
seems to save things we don't need, and that could make us overly conservative.

It turns out that this new scheduling discipline makes the old space-time scheduler perform
better than the new stochastic space-time scheduler on systems with fewer than 4 cores. This is
because the mutator having the conn enables us to time the mutator<->collector context switches
by polling. The OS is never involved. So, we can use super precise timing. This allows the old
space-time schduler to shine like it hadn't before.

The splay results imply that this is all a good thing. On 2-core systems, this reduces pause
times by 40% and it increases throughput about 5%. On 1-core systems, this reduces pause times by
half and reduces throughput by 8%. On 4-or-more-core systems, this doesn't seem to have much
effect.

Air should have a disassembly mode that dumps IR and assembly intermixed
https://bugs.webkit.org/show_bug.cgi?id=168629

Reviewed by Filip Pizlo.

This will make dumping FTL disassembly dump Air intermixed
with the assembly generated by each Air Inst. This is similar
to how dumpDFGDisassembly dumps the generated assembly for each
Node.

Here is what the output will look like:
