The assembler has 8 different vmov variants. The one for vmov.32 and for moving
an immediate into a double reg only differs in the type of the second
paremeter: vmov.32 takes an int, the other takes a double.

The situation is dangerous because C++ will happily implicitly convert between
int and double.

This patch changes the signature of the vmov.32 assembler function so that it
cannot be confused with the other vmovs.

This allows Crankshaft to completely inline a f.apply() dispatch if the
exact number of arguments is known and the function is constant. The
deoptimizer doesn't generate the f.apply() frame during deoptimization,
so the materialized frames look like f.apply() did a tailcall.

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.

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.

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.

This is not only inherently slow, but it also forces the caller to enter an
Isolate before. Both is bad, so we have to do some heap plumbing.

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.

Simplified the HeapStatistics class a bit, following Uncle Bob's advice that
adding accessors to DTOs only satisfies some design fundamentalists, but serves
no other purpose. :-)
