0c3575c874 Generate the TransitionElementsStub using Crankshaft 
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.

1c1fdc7da2 Better fix for MemoryChunk::owner(). 
Pointer arithmetic such as "owner_ - kFailureTag" is undefined behaviour
unless owner_ points to a valid object.

This allowed Clang to assume the subtraction would never be NULL,
causing problems in the caller (see https://codereview.chromium.org/12090072/).

To fix this, we should cast owner_ to intptr_t before doing the
arithmetic.

672056ac88 Only mark the descriptor that is valid for the map in question. If this map 
transitioned from a map with a different descriptor array (or has no back
pointer), mark all valid descriptors from the start.

This fixes the following memory leak: Map A shares a descriptor array
with map B. Map B adds constant function c that in its scope holds on to
an instance of B. If the descriptor array of A would keep all the shared
descriptors alive, including c, this keeps alive both A and c
indefinitely.

This CL also fixes a bug in descriptor array trimming. When trimming
descriptor arrays we need to trim off the slack as well (thus the entire
storage); and since we are trimming a descriptor array, we need to trim
* kDescriptorSize.

c001d928df Object.observe: don't unnecessarily emit oldValue for reconfigurations of data properties 
When a data property has its attributes changed but its value remains the same,
don't emit an oldValue. This makes the API more consistent by only emitting
oldValue when the value of a property has actually changed (or been removed,
in the case of a reconfiguration as an accessor property or a deletion).

e7420f65bc Also allow the empty object map to keep transitions. 
With the old implementation, due to the map-check being inadequate, such
transitions were already added for cross-context field stores. It is not
necessary anymore to not store transitions, since we properly clear
non-live transitions. Globally enabling this feature will help find more
bugs.

8a86ce7ef6 Do not duplicate the compilation pipeline for stub compilation.

least this CL is a step in the right direction...
