Add /api/measurement-set for v3 UI
https://bugs.webkit.org/show_bug.cgi?id=152312

Rubber-stamped by Chris Dumez.

The new API JSON allows the front end to fetch measured data in chunks called a "cluster" as specified
in config.json for each measurement set specified by the pair of a platform and a metric.

When the front end needs measured data in a given time range (t_0, t_1) for a measurement set, it first
fetches the primary cluster by /api/measurement-set/?platform=<platform-id>&metric=<metric-id>.
The primary cluster is the last cluster in the set (returning the first cluster here is not useful
since we don't typically show very old data), and provides the information needed to fetch other clusters.

Fetching the primary cluster also creates JSON files at:
/data/measurement-set-<platform-id>-<metric-id>-<cluster-end-time>.json
to allow latency free access for secondary clusters. The front end code can also fetch the cache of
the primary cluster at: /data/measurement-set-<platform-id>-<metric-id>.json.

Because the front end code has to behave as if all data is fetched, each cluster contains one data point
immediately before the first data point and one immediately after the last data point. This avoids having
to fetch multiple empty clusters for manually specified baseline data. To support this behavior, we generate
all clusters for a given measurement set at once when the primary cluster is requested.

Furthermore, all measurement sets are divided at the same time into clusters so that the boundary of clusters
won't shift as more data are reported to the server.

* config.json: Added clusterStart and clusterSize as options.
* public/api/measurement-set.php: Added.

(MeasurementSetFetcher::__construct):
(MeasurementSetFetcher::fetch_config_list): Finds configurations that belongs to this (platform, metric) pair.

the need to have key names for each measurement and reduces the JSON size by ~10%.

REGRESSION (r192375): DumpRenderTree.app exits immediately with no error
<http://webkit.org/b/152314>

Reviewed by Daniel Bates.

The change to DumpRenderTreeMain.mm in r192375 caused the iOS
code path to exit immediately when calling main().
Unfortunately, DumpRenderTreeMain.mm was used for both
DumpRenderTree command-line binary and DumpRenderTree.app, which
meant that the app would exit immediately with no error code
when run!

The workaround is to introduce a separate source file called
DumpRenderTreeAppMain.mm, similar to what WebKitTestRunner
already does.

      "abc" | 0; // would yield "abc" instead of the expected 0 if we let

FTL B3 should account for localsOffset
https://bugs.webkit.org/show_bug.cgi?id=152288

Reviewed by Saam Barati.

The DFG will build up some data structures that expect to know about offsets from FP. Those data
structures may slide by some offset when the low-level compiler (either LLVM or B3) does stack
allocation. So, the LLVM FTL modifies those data structures based on the real offset that it gets
from LLVM's stackmaps. The B3 code needs to do the same.

I had previously vowed to never put more stuff into FTLB3Compile.cpp, because I didn't want it to
look like FTLCompile.cpp. Up until now, I was successful because I used lambdas installed by
FTLLower. But in this case, I actually think that having code that just does this explicitly in
FTLB3Compile.cpp is least confusing. There is no particular place in FTLLower that would want to
care about this, and we need to ensure that we do this fixup before we run any of the stackmap
generators. In other words, it needs to happen before we call B3::generate(). The ordering
constraints seem like a good reason to have this done explicitly rather than through lambdas.

I wrote a test. The test was failing in trunk because the B3 meaning of anchor().value() is
different from the LLVM meaning. This caused breakage when we used this idiom:

    ValueFromBlock foo = m_out.anchor(things);
    ...(foo.value()) // we were expecting that foo.value() == things

I never liked this idiom to begin with, so instead of trying to change B3's anchor(), I changed
the idiom to:

    LValue fooValue = things;
    ValueFromBlock foo = m_out.anchor(fooValue);
    ...(fooValue)

This is probably a good idea, since eventually we want B3's anchor() to just return the
UpsilonValue*. To get there, we want to eliminate any situations where code assumes that
ValueFromBlock is an actual object and not just a typedef for a pointer.

Math.random should have an intrinsic thunk and it should be later handled as a DFG Node

Reviewed by Geoffrey Garen.

Source/JavaScriptCore:

In this patch, we implement new RandomIntrinsic. It emits a machine code to generate random numbers efficiently.
And later it will be recognized by DFG and converted to ArithRandom node.
It provides type information SpecDoubleReal since Math.random only generates a number within [0, 1.0).

Currently, only 64bit version is supported. On 32bit environment, ArithRandom will be converted to callOperation.
While it emits a function call, ArithRandom node on 32bit still represents SpecDoubleReal as a result type.

B3 should not give ValueReps for the non-stackmap children of a CheckValue to the generator callback
https://bugs.webkit.org/show_bug.cgi?id=152224

Reviewed by Geoffrey Garen.

Previously, a stackmap generator for a Check had to know how many children the B3 value for the
Check had at the time of code generation. That meant that B3 could not change the kind of Check
that it was - for example it cannot turn a Check into a Patchpoint and it cannot turn a CheckAdd
into a Check. But just changing the contract so that the stackmap generation params only get the
stackmap children of the check means that B3 can transform Checks as it likes.

This is meant to aid sinking values into checks.

Also, I found that the effects of a Check did not include HeapRange::top(). I think it's best if
exitsSideways does not imply reading top, the way that it does in DFG. In the DFG, that makes
sense because the exit analysis is orthogonal, so the clobber analysis tells you about the reads
not counting OSR exit - if you need to you can conditionally merge that with World based on a
separate exit analysis. But in B3, the Effects object tells you about both exiting and reading,
and it's computed by one analysis. Prior to this change, Check was not setting reads to top() so
we were effectively saying that Effects::reads is meaningless when exitsSideways is true. It
seems more sensible to instead force the analysis to set reads to top() when setting
exitsSideways to true, not least because we only have one such analysis and many users. But it
also makes sense for another reason: it allows us to bound the set of things that the program
will read after it exits. That might not be useful to us now, but it's a nice feature to get for
free. I've seen language features that have behave like exitsSideways that don't also read top,
like an array bounds check that causes sudden termination without making any promises about how
pretty the crash dump will look.

This adds really awesome architecture selection to the AirOpcode.opcodes file. If an opcode or
opcode form is unavailable on some architecture, you can still mention its name in C++ code (it'll
still be a member of the enum) but isValidForm() and all other reflective queries will tell you
that it doesn't exist. This will make the instruction selector steer clear of it, and it will
also ensure that the spiller doesn't try to use any unavailable architecture-specific address
forms.

The new capability is documented extensively in a comment in AirOpcode.opcodes.

B3->Air compare-branch fusion should fuse even if the result of the comparison is used more than once
https://bugs.webkit.org/show_bug.cgi?id=152198

Reviewed by Benjamin Poulain.

If we have a comparison operation that is branched on from multiple places, then we were
previously executing the comparison to get a boolean result in a register and then we were
testing/branching on that register in multiple places. This is actually less efficient than
just fusing the compare/branch multiple times, even though this means that the comparison
executes multiple times. This would only be bad if the comparison fused loads multiple times,
since duplicating loads is both wrong and inefficient. So, this adds the notion of sharing to
compare/branch fusion. If a compare is shared by multiple branches, then we refuse to fuse
the load.

To write the test, I needed to zero-extend 8 to 32. In the process of thinking about how to
do this, I realized that we needed lowerings for SExt8/SExt16. And I realized that the
lowerings for the other extension operations were not fully fleshed out; for example they
were incapable of load fusion. This patch fixes this and also adds some smart strength
reductions for BitAnd(@x, 0xff/0xffff/0xffffffff) - all of which should be lowered to a zero
extension.

This is a big win on asm.js code. It's not enough to bridge the gap to LLVM, but it's a huge
step in that direction.

[iOS] DOM click event may not be dispatched when page has :active style and <input type="search">
https://bugs.webkit.org/show_bug.cgi?id=144451
<rdar://problem/23099482>

Patch by Daniel Bates <dabates@apple.com> on 2015-12-14
Reviewed by Simon Fraser.

Source/WebCore:

Fixes an issue where a DOM click event is not dispatched to an element in a subframe on a page
that has a <input type="search"> and defines a CSS :active pseudo-class for the HTML body element.

On iOS we only dispatch a DOM click event if the content of the page does not change as part of
dispatching a DOM mousemove event at the tapped element as a means of providing a good user
experience on web pages that reveal or hide content based on mouse hover. Currently we consider
the content of the page to have changed if the visibility of any element on the page changes.
In particular we consider the content of the page to have changed if the visibility of a user
agent shadow DOM element changes (e.g. the search field cancel button). Instead we should only
consider visibility changes to the actual web page content and ignore visibility changes to
user agent shadow DOM elements.

Additionally, add tests to ensure we update the cancel button visibility whenever the visibility
of the search field changes.

[JSC] Should not emit get_by_id for indexed property access
https://bugs.webkit.org/show_bug.cgi?id=151354

Reviewed by Darin Adler.

Before this patch, `a["1"]` is converted to `a.1` get_by_id operation in the bytecode compiler.
get_by_id emits IC. IC rely on the fact that Structure transition occur when adding / removing object's properties.
However, it's not true for indexed element properties. They are stored in the element storage and Structure transition does not occur.

For example, in the following case,

     function getOne(a) { return a['1']; }

     for (var i = 0; i < 36; ++i)
         getOne({2: true});

     if (!getOne({1: true}))
         throw new Error("OUT");

In this case, `a['1']` creates get_by_id. `getOne({2: true})` calls makes getOne's get_by_id to create IC says that,
"when comming this structure chain, there is no property in "1", so we should return `undefined`".

After that, we call `getOne({1: true})`. But in this case, `{2: true}` and `{1: true}` have the same structure chain,
because indexed property addition does not occur structure transition.
So previous IC fast path is used and return `undefined`. But the correct answer is returning `true`.

This patch fixes the above issue. When there is string bracket access, we only emits get_by_id if the given string is not an index.
There are bugs in get_by_id, put_by_id, put_by_id (direct). But only get_by_id poses user observable issue.
Because in the put_by_id case, the generic path just says "this put is uncacheable".

sequence, except in anonymous heap memory instead of delicious file-backed pages.

Care is taken to ensure that the wrapper StringImpl is updated to target newly cached
resource data if an asynchronous caching notification comes in.

Clean up absolute positioned map properly.

rdar://problem/23861165

Reviewed by Simon Fraser.

We insert positioned renderers into a static map (RenderBlock::gPositionedDescendantsMap) to keep track of them.
Since this static map is at block level, (positioned)inline renderers use their containing block to store
their positioned descendants.
This patch ensures that when an inline element can no longer hold positioned children, we remove them from
the inline's containing block's map. -unless the container itself can hold positioned renderers(see RenderElement::canContainAbsolutelyPositionedObjects).

[JSC] Add Floating Point Abs() to B3
https://bugs.webkit.org/show_bug.cgi?id=152176

Patch by Benjamin Poulain <bpoulain@apple.com> on 2015-12-11
Reviewed by Geoffrey Garen.

This patch adds an Abs() operation for floating point.

On x86, Abs() is implemented by masking the top bit
of the floating point value. On ARM64, there is a builtin
abs opcode.

To account for those differences, B3 use "Abs" as
the cannonical operation. When we are about to lower
to Air, Abs is extended on x86 to get a clean handling
of the mask constants.

This patch has one cool thing related to FTL.
If you do:
   @1 = unboxDouble(@0)
   @2 = abs(@1)
   @3 = boxDouble(@2)

B3ReduceStrength completely eliminate the Double-Integer
conversion.

The strength reduction of Abs is aware that it can do a bit
mask over the bitcast used by unboxing.
If even works if you use floats by forcing fround: reduceDoubleToFloat()
elminiates the useless conversions, followed by ReduceStrength
that removes the switch from GP to FP.
