B3 Patchpoint and Check opcodes should be able to specify WarmAny, ColdAny, and LateColdAny
https://bugs.webkit.org/show_bug.cgi?id=151335

Reviewed by Geoffrey Garen.

This removes ValueRep::Any and replaces it with ValueRep::WarmAny, ValueRep::ColdAny, and
ValueRep::LateColdAny. I think that conceptually the most obvious users of patchpoints are inline
caches, which would use WarmAny for their non-OSR inputs. For this reason, I make WarmAny the
default.

However, the StackmapValue optimization that provides a default ValueRep for any that are missing
was meant for OSR. So, this optimization now uses ColdAny.

This patch wires this change through the whole compiler and adds some tests.

B3 patchpoints should allow specifying output constraints
https://bugs.webkit.org/show_bug.cgi?id=151809

Reviewed by Benjamin Poulain.

JS call patchpoints should put their result into the result register, while most other patchpoints
should put their results into some register. I think that it's best if we just allow arbitrary
constraints on the result of a patchpoint. And by "arbitrary" I mean allowing the same kinds of
constraints as we allow on the stackmap children.

This also adds a large comment in B3StackmapValue.h that lays out the philosophy of our stackmaps
and patchpoints. I found it useful to write down the plan since it's pretty subtle.

Reviewed by Geoffrey Garen.

There were a few fields on FTL::OSRExitDescriptor that are only
needed during compilation. This patch introduces OSRExitDescriptorImpl
which is a struct that we create for each OSRExitDescriptor. The difference is
that OSRExitDescriptorImpl lives off of FTL::State so it dies after we compile.
This way no unnecessary fields persist after the compilation.

[Win] fast/forms/HTMLOptionElement_label03.html failing on win7
https://bugs.webkit.org/show_bug.cgi?id=150909
rdar://problem/23539673

Patch by Keith Rollin <krollin@apple.com> on 2015-12-03
Reviewed by Darin Adler.

Source/WebCore:

When returning text to be displayed, an <option> element will return
the value of a label attribute if it exists, or the text content as a
fallback. The failing test concerned the display of a <select>
element when it contained a sole <option> element that had a label
attribute set to a single space. When displayed, various
platform-specific bits of code will strip off the leading and trailing
whitespace. However, when WebKit would use this text to measure how
wide the <select> popup menu button should be, it would not strip off
spaces, leading to the calculated width being wider than necessary.
The approach taken to fix this is to strip whitespace in the label
attribute before it is returned from the <option> element.

No new tests. fast/forms/HTMLOptionElement_label03.html had been
marked as being expected to fail in TestExpectations; that test now
succeeds.

FTL B3 should support OSR exit
https://bugs.webkit.org/show_bug.cgi?id=151710

Reviewed by Saam Barati.

Source/JavaScriptCore:

This adds OSR exit support using the same style that I established with lazy slow paths. All of
the work is driven by FTL::LowerDFGToLLVM, and from there any work that needs to be deferred
until after B3 finishes is attached to the stackmap generator. In order to make it easy to port
all of the different forms of OSR exit - invalidation points, exceptions, etc. - the logic for
registering an OSR exit is abstracted behind OSRExitDescriptor and OSRExitHandle.

An issue that I encountered repeatedly in this patch is OSRExitDescriptor being passed as a
reference (&) rather than pointer (*). The new code uses a lot of lambdas that run after the
current frame pops, so the capture list cannot be [&]. I believe that always listing all of the
captured variables is not scalable considering how sophisticated our use of lambdas is. So, it
makes sense to use [=]. But anytime we captured a variable whose type was OSRExitDescriptor&, it
would be captured by value, because that's how references work. One has to be mindful of these
things whenever using [=]. Note that it's not enough to say that we should have listed the
captured variables explicitly - in that case, we still could have made the mistake by forgetting
to put & in front of the variant. The pattern that worked for me to reason about whether I'm
capturing an object or a pointer to an object is to always use pointer types for pointers: either
RefPtr<> when we also want the lambda to prolong the object's life, or * if we are confident that
the object will stay alive. For this reason, this patch changes all code that references
OSRExitDescriptor to use * instead of &. Consistency makes the code easier to grok, and it made
it easier to introduce the required uses of * in places where there were lambdas.

I tested this by running imaging-gaussian-blur, and running some tests that reqiure OSR exit. I'm
not promising that all kinds of exits work, but we have to begin somewhere.

Reviewed by Alex Christensen.

STL reverse_iterators are a tricky beast.

They are implemented in terms of a normal forward iterator (called the "base" iterator),
and they decrement a copy of that iterator when dereferenced.

So when monitoring deletes from a std::set to check if we should invalidate our current
reverse_iterator, we were incorrectly comparing the deleted key to the value pointed by the
reverse_iterator instead of its base iterator.

Since the iterators in question are bidirectional, anyways, we can just use a single iterator
and either increment or decrement it as needed.

No new tests (At least one failing (crashing) test now passes).

[iOS] Fullscreen -> PiP should resume to Fullscreen, not inline
https://bugs.webkit.org/show_bug.cgi?id=150906

Reviewed by Simon Fraser.

Source/WebCore:

When restoring the user interface when exiting PiP, we should return to Fullscreen if that
is where fullscreen was initiated from. Additionally, when we "auto-PiP" by backgrounding the
app in Fullscreen mode, we should "auto-un-PiP" when restoring the application to foreground.

Rather than have a separate method to request exiting fullscreen, entering standard fullscreen,
and switching to & from PiP, add a new method setFullscreenMode() which does all three.

Polymorphic operand types for DFG and FTL mul.
https://bugs.webkit.org/show_bug.cgi?id=151746

Reviewed by Filip Pizlo.

Source/JavaScriptCore:

Perf on benchmarks is neutral except for the newly added JSRegress ftl-object-mul
test which shows a 2.16x speed up on x86_64 FTL, 1.27x speed up on x86_64 DFG,
and 1.56x on x86 DFG.

The speed up comes not from the mul operator itself, but from the fact that the
polymorphic operand types support now allow the test function to run without OSR
exiting, thereby realizing the DFG and FTL's speed up on other work that the test
function does.

This patch has passed the layout tests on x86_64 with a debug build.

Add a setting and restriction which will pause invisible autoplaying video

Reviewed by Eric Carlson.

Source/WebCore:

Test: media/video-restricted-invisible-autoplay-not-allowed.html

Drive-by fix: m_autoplaying is reset in many places by calling pause() or play(), where those
calls did not originate from an explicit request to pause or play, e.g., during an interruption.
This causes m_autoplaying to be set to false, thus breaking resumption of autoplaying when the
interruption ends. Update PlatformMediaSession to remember its client's "autoplaying" state and
restore it when an interruption ends.

Add a means to register for viewport visibility notifications to FrameView, RenderView,
and RenderElement. Elements who wish to recieve these notifications must do so through their
renderer, and thus will have to re-register whenever a new renderer is attached.

Add a restriction to HTMLMediaElement which will pause autoplaying video when that video scrolls
out of the viewport, or is hidden with CSS.

Add a setting which controls whether that new restriction is set.

[css border] border-image doesn't honor border-style

Reviewed by Simon Fraser.

https://bugs.webkit.org/show_bug.cgi?id=151519

Reviewed by Geoffrey Garen.

One detail about how we choosing to handle operands to the binary snippets that
may be constant: the slow path call to a C++ function still needs the constant
operand loaded in a register.  To simplify things, we're choosing to always tell
LLVM to load the operands into registers even if they may be constant.  However,
even though a constant operand is preloaded in a register, the snippet generator
will not be made aware of it.  It will continue to load the constant as an
immediate.

[JSC] Handle x86 partial register stalls in Air
https://bugs.webkit.org/show_bug.cgi?id=151735

Patch by Benjamin Poulain <bpoulain@apple.com> on 2015-12-02
Reviewed by Filip Pizlo.

This patch adds a primitive false-dependency breaking
algorithm to Air. We look for redefinition of the same
variable that is too close to a partial definition.

There is not explicit dependency tracking going on,
but it is pretty fast and the extra xorps added on false-positives
are cheap anyway.

Typically, partial register stalls appear from instructions
interfering with themselves in small loops. Something like:

  Label0:
    cvtsi2sdq %eax, %xmm0
    ...
    jmp Label0

Those are correctly detected by propagating the local distance
information from block to block until no unsafe chain is found.

The test testInt32ToDoublePartialRegisterStall() checks the kind
of cases we typically find from JavaScript.
The execution time is 20% faster with a register reset (which is
astounding since the very next instruction has a real dependency).

Future tweaks will be needed when we can run more JavaScript:
-Handle function calls differently.
-Anything with a special can have hidden instructions.
We need to take them into account.
