Delivery logic for Object.observe
This CL has two parts: the first is the logic itself, whereby each observer callback is assigned
a "priority" number the first time it's passed as an observer to Object.observe(), and that
priority is used to determine the order of delivery.
The second part invokes the above logic as part of the API, when the JS stack winds down to
zero.
Added several tests via the API, as the delivery logic isn't testable from a JS test
(it runs after such a test would exit).

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.
