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.

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.

Fix type inference for i-to-t change instruction. On X64 this ensures that write-barrier is generated correctly.
