eb573e1122 MIPS: Generate the TransitionElementsStub using Crankshaft 
Port r13585 (4174b9d2)

Original commit message:
This includes:
* Adding support for saving callee-clobbered double registers in Crankshaft code.
* Adding a new "HTrapAllocationMemento" hydrogen instruction to handle AllocationSiteInfo data in crankshafted stubs.
* Adding a new "HAllocate" hydrogen instruction that can allocate raw memory from the GC in crankshafted code.
* Support for manipulation of the hole in HChange instructions for Crankshafted stubs.
* Utility routines to manually build loops and if statements containing hydrogen code.

9bb68394a0 Fix code flusher disabling while marking incrementally. 
This fixes a corner case where the code flusher is disabled while the
incremental marker is still running. This can happen when the debugger
is loaded and a scavenge is triggered. Make sure that all flushing
decisions are revisited after the candidates lists are evicted.

5aafde9285 Print deoptimization index when printing lithium environment. 
Output of --trace-deopt --code-comments does not always allow to reliably match deoptimization to the lithium instruction (and it is actually never accurate on x64 due to one level of indirection). This change allows to reliably figure out which instruction deoptimized just by looking up bailout id in the hydrogen.cfg.

ec0b001543 Work around nifty VS10 compiler bug 
VS10 generates bogus code for specific arguments to the Number::New function when invoked in specific places of an ExpectRecords array definition, passing a garbage value to the function (as printf debugging reveals). Changing the argument from 1 to 7 apparently circumvents the problem.

1e90596702 Simplify secure API functions workaround for MinGW 
If MINGW_HAS_SECURE_API is defined, the definitions of localtime_s,
fopen_s, _vsnprintf_s, strncpy_s had to be renamed using #define
so they would not conflict with definitions in the standard headers.

A simpler way to handle this is to undefine MINGW_HAS_SECURE_API before
including the standard headers.

f08b6ecac7 Split CompileCallConstant into logical parts for Frontend and Backend. 
Initial step towards separating IC (map check(s)), handler frontend
(prototype-check) and handler backend (actual handler code).

- Still need to split the map-check (IC) from rest of the prototype
  chain check.
- Still need to turn different parts in own code objects and cache them
  in more optimal places.

6ab7a23f6c Object.observe: use JSWeakMaps instead of raw ObjectHashTables in observation state 
object-observe.js uses weak maps to add "hidden" properties to
objects. Previously, the hash tables it was using weren't actually
weak. This patch changes the existing runtime functions to create
instances of JSWeakMap instead of exposing ObjectHashTable directly.
