Faster string equals in generated code.
...
In my previous change I mixed up "compare" and "equals". This made us
miss the fast length check before comparing strings for equality.
Now we have a separate helper for "equals". It shares some of the
inner loop details with "compare". I'll see if this can be cleaned up
without making it unreadable.

The only difference to revision 7763 is the implementation in the

and Array.prototype.toLocaleString from should throw on null or

Change heuristics for deciding phi-representation types to use int32 more frequently.
...
Until now we conservatively chose a double representation if
at least one use occurs in a double operation. This causes performance
degradation in many cases where there are mixes uses (integer and double)
e.g.:
for (int i = 0; i < 10; i++) {
var t = i / 3.5;
a[i] = t;
}
where the use in i/3 requires a double, where as the keyed store requires i
as an integer.
For these cases we want to have i as an integer and convert it only before the
double division.
In order to avoid unconditional deoptimization in some rare cases, we check
phis if there is any conversion that will always fail when converting a
heap-number constant to int32.

ARM: Changed the handling of compiletime CPU feature detection
...
Always use CpuFeaturesImpliedByCompiler() when selecting CPU features. This checks both for CAN_USE_ARMV7_INSTRUCTIONS and CAN_USE_VFP_INSTRUCTIONS and for GCC preprocessor symbols. This will support using the CAN_USE_XXX for a simulator build used for generating a snapshot followed by a crosscompile using -march= and -mfpu= for selecting the (minimal) target device CPU features. The snapshot will use instructions based on the CAN_USE_XXX whereas the target will at least use features based on both CAN_USE_XXX and -march= and -mfpu=, but will try runtime CPU feature detection a well looking for somethis better.
Remove the compiler based CPU feature detection from the OS::CpuFeaturesImpliedByPlatform() as it did not belong there. Also was already in the CpuFeaturesImpliedByCompiler().
Add the variable 'v8_can_use_vfp_instructions' to the GYP file which can be used to turn on CAN_USE_VFP_INSTRUCTIONS when building V8. I did not add any -mfpu= cflags for this, as there are several options here (e.g. vfp and neon).

ll_prof: Reduce profiling hooks overhead from >400% to 25%.

Switched to using binary low-level log instead of the textual log used
by the ticks processor. The binary log contains code-related events,
code object names, and their bodies. When writing to the log we ask
glibc to use a larger buffer. To avoid complex processing of the
snapshot log (which is still textual) the serializer emits final
snapshot position to code name mappings that can be quickly be read
without replaying the snapshot log. (This might be useful for the
ticks processor.)

The "simple" function with inline assembly for detecting hardfloat have been changed to handle compiling without VFP and with thumb.
The SCons setting for the float abi now follows then naming used by the GCC -mfloat-abi and soft has been added.

Add support for startup data (snapshot) compression.
...
This is for mobile platforms where application footprint size is
important. To avoid including compression libraries into V8, we assume
that the host machine have them (true for Linux), and rely on embedder
to provide decompressed data.
Currently, only snapshot data can be comressed. It is also possible to
compress libraries sources, but it is more involved and will be
addressed in another CL.

ARM: Support hardfloat in SCons build and make it a build time setting
...
Add option armeabi to the SCons build for selecting the floating point variant to use. Also add externally defined CCFLAGS environment for all targets. Run test.py with option -S armeabi=hardfloat to test with hardfloat enabled.
Make selecting hardfloat EABI variant a build-time option instead of a runtime option.
Add a simple check of the EABI variant during V8 initialization to exit if the compilation was not configured correctly. The reason for this is that GCC does not provide a compile time symbol defining the EABI variant. This check is not fool-proof as it cannot check the compilation configuration used for the snapshot if any.

Change the Hydrogen representation of uses.
...
Rather than representing a use as a pointer to an HValue and then searching
for the specific (ambiguous) operand, we now represent a use as a pair of an
HValue and the input operand index. Additionally, use a linked list instead
of a growable array list since we never use random access.
This allows us to remove a bunch of similarly named and subtly different
functions from the HValue API. The cost in extra zone allocation per use is
partially offset by reusing use list nodes when replacing a use of one value
with another.

Reduce the number of virtual function in hydrogen-instruction.h classes
...
Instead of using virtual type-tester functions we can just
generate non-virtual ones for all concrete IR classes.
This is changes reduces the V8 binary size by ~2%.
I also simplified the macros to declare new hydrogen instructions slightly.
The name used for debug output is no longer passed as a separate string.
Instead we just use the class name.

ChromeOS and Chrome need this feature for M12. This could be added as chrome extension API. Giiven that we have a rough agreement on the collation part of ECMAScript API, we thought it'd save us some duplicated work adding this to v8 (experimental i18n api) now rather than implementing it in Chrome now and moving it later.

2. Use-at-start policy (register, memory or constant).

not specifying use-at-start prevents the allocator from using
a register even if there is one available. That's why use-at-start
is required and guarded by assertion)

Change the list of statements that are inlineable into a black-list.
...
Before we had a white-list of things that we allow inside inlined functions.
This way we can enable new constructs one-by-one.

Cleanup of ScannerConstants, now named UnicodeCache.
...
The ScannerConstants class was originally static fields on the scanner class.
During creation of the stand-alone preparser and later isolates, it has been
moved into a separate class with a per-isolate instance.
It is used to hold caching unicode Predicate values.
This change renames the class to UnicodeCache, and passes a reference
to the instance down to methods that doesn't have an easy access to
an isolate (to avoid, e.g., having to do an Isolate::Current() for every
number parsed).

Do not rely on uniqueness of pthread_t
...
Patch by Dmitry Lomov.
pthreads implementations are free to reuse pthread_t (thread id) after
the thread has died. This change gets rid of ThreadHandle class and
replaces it with v8-managed thread identifiers.
