MIPS: fix mips_arch_variant bug in GYP build.
There is a small bug that causes to build mips32r2
version of v8 as mips32 (r1). This affects only
the compiled code.
In the default case of building for mips32r2,
the compiler flags are the following:
-EL -mhard-float -mips32r2 -Wa,-mips32r2 -mips32 -Wa,-mips32
Since the "last flag wins" the object files are
compiled as mips32. In a funny twist, the
code sourcery lite compilers do not have multi-lib support,
and there is a bug that if you tell it to link mips32,
it will silently link the object files with
mips32r2 libraries, and then the resulting binary is mips32r2.
This commit fixes the mips32r1/mips32r2 build.

Port r12373 (

Original commit message:
Fix DoDeferredNumberTagU to keep the value in xmm1 instead of xmm0 on x64.
xmm0 is not saved across runtime call on x64 because MacroAssembler::EnterExitFrameEpilogue preserves only allocatable XMM registers unlike on ia32 where it preserves all registers.
Cleanup handling of shifts: SHR can deoptimize only when its a shift by 0, all other shift never deoptimize.
Fix type inference for i-to-t change instruction. On X64 this ensures that write-barrier is generated correctly.

Implement committed physical memory stats for Linux.
The patch introduces CommittedPhysicalMemory function to
the Heap class that reports committed *physical* memory acquired
for the heap from the OS.
It is important because some OSes may defer actual committment on e.g.
first access to the region.
So reporting just plain committed size led to various weird artifacts
like showing V8 allocated memory higher than the whole process
private size.

The previously-used instruction isn't guaranteed to always be undefined,
and the encoding used was conditional (failing the condition on an
undefined instruction is itself undefined and not guaranteed to

Use movw/movt instead of constant pool on ARMv7.
Some ARM architectures load 32-bit immediate constants more efficiently using movw/movt pairs rather than constant pool loads. This patch allows the assembler to generate one or the other load form at runtime depending on what is faster.

Add an API for enumerating persistent handles
This API lets the embedder enumerate handles that have class ids. WebKit will
use this feature during garbage collection to compute object groups for DOM
nodes. Previously, we kept a list of DOM nodes on the WebKit side, but that
list is redundant with the global handles list in V8.
