Description:
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.
