675e711f1c Cardmarking writebarrier.
- New сardmarking write barrier handles large objects and normal objects in a similar fashion (no more additional space for pointer tracking is required, no conditional branches in WB code).
- Changes to enable oldspaces iteration without maps decoding:
-- layout change for FixedArrays: length is stored as a smis (initial patch by
Kevin Millikin)
-- layout change for SharedFunctionInfo: integer fields are stored as smi on
arm, ia32 and rearranged on x64.
-- layout change for String: meaning of LSB bit is fliped (1 now means hash not
computed); on x64 padding is added.
-- layout of maps is _not_ changed. Map space is currently iterated in a special
way.

8879691793 Cardmarking writebarrier.
Reapplication of r4685 (reviewed http://codereview.chromium.org/2101002) with minor modifications:

- Fix compilation problems on Win64.
- Improve heap verification pass: search for garbage pointers to new space not only in dirty regions but in all regions.

19d98493fc Add complete implementation of full compiler for the ia32 architecture
This makes the full compiler handle all constructs on ia32. However the syntax checker for the full compiler is still the same so for both normal operation and with the flag --always-full-compiler the coverage of the full compiler will be the same.

This is on preparation for improving the debugger break point experience where the plan is to only use code from full code generator when debugging JavaScript.

Runs all tests on all three platforms in release and debug mode. The tests also run with both the following flags to the test runner

  --special-command="@ --nofull-compiler"
  --special-command="@ --always-full-compiler"

The changes to the x64 and ARM architectures are mainly structural due to the change to EmitVariableAssignment to handle initialization of const variables.

e9b5d7855b Allow build-time selection between ia32 and x86_64 in the GYP/Xcode Mac
Chromium build.

v8.gyp no longer sets any V8_TARGET_ARCH_* macro on the Mac. Instead, the
proper V8_TARGET_ARCH_* macro will be set by src/globals.h in the same way as
the V8_HOST_ARCH_* macro when it detects that no target macro is currently
defined. The Mac build will attempt to compile all ia32 and x86_64 .cc files.
#ifdef guards in each of these target-specific source files prevent their
compilation when the associated target is not selected. For completeness,
these #ifdef guards are also provided for the arm and mips .cc files.

BUG=706
TEST=x86_64 Mac GYP/Xcode-based Chromium build (still depends on other changes)
