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).

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.

Remove support for inlined property loads and stores.
The full code generator does not generate inline code for
property loads and stores. All this code is unused with
Crankshaft.

Support string add in crankshaft:
o The type recording binary stub got a new type for string + string.
o Added HStringAdd and LStringAdd based on the new type info.
o Started using HValue types to avoid unneccesary checks.

Add v8Locale.Collator
This is a partial implementation of Collator per what's agreed upon at the last
ECMAScript meeting + mailing list. Only the following three options are implemented: ignoreAccent, ignoreCase, numeric.
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.

Refine allocation policy for input operands at calls.
For instructions that are marked as calls we can use:
1. Fixed input registers
2. Use-at-start policy (register, memory or constant).
(Memory or constant would not need the use-at-start policy, but
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)
