b80cbd7922 Object.observe: generate change records for named properties. 
In more detail:
- Set observation bit for observed objects (and make NormalizedMapCache respect it).
- Mutation of observed objects is always delegated from ICs to runtime.
- Introduce JS runtime function for notifying generated changes.
- Invoke this function in the appropriate places (including some local refactoring).
- Inclusion of oldValue field is not yet implemented, nor element properties.

Also, shortened flag to --harmony-observation.

f3807ca17b Heavy cleanup of the external pointer API. 
Added highly efficient Object::SetAlignedPointerInInternalField and
Object::GetAlignedPointerFromInternalField functions for 2-byte-aligned
pointers. Their non-aligned counterparts Object::GetPointerFromInternalField and
Object::SetPointerInInternalField are now deprecated utility functions.

External is now a true Value again, with New/Value/Cast using a JSObject with an
internal field containing a Foreign. External::Wrap, and External::Unwrap are now
deprecated utility functions.

Added Context::GetEmbedderData and Context::SetEmbedderData. Deprecated
Context::GetData and Context::SetData, these are now only wrappers to access
internal field 0.

Added highly efficient Context::SetAlignedPointerInEmbedderData and
Context::GetAlignedPointerFromEmbedderData functions for 2-byte-aligned

9de1d40d28 Improve handling of property loads on the proto chain. 
Previously Crankshaft emitted a generic load for these, now we emit a load of a
named field, guarded by a proto chain check.

LCheckPrototypeMaps now returns the holder, which is for free, because it
already had to check its map as the last step, anyway. This is in sync with what
StubCompiler::CheckPrototype does.

8daf7e7de1 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.

60267da6d9 MIPS: Cleanup handling of shifts: SHR can deoptimize only when its a shift by 0, all other shift never deoptimize. 
Port r12373 (9fdde2ad)

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.

ebb44f0d30 Expose gc(true) to JavaScript, which triggers a scavenger GC. 
With the --expose_gc option, gc() is exposed to JavaScript. Currently gc() triggers a full GC.

To enable JavaScript to test the behavior of a scavenger GC, this patch exposes gc(true). If the first argument is true, gc(...) triggers a scavenger GC. Otherwise, gc(...) triggers a full GC.

BUG=
Test=Manually confirmed that gc() and gc(false) trigger a full GC and that gc(true) triggers a scavenger GC.
