6e4a8fecb7 Two bugfixes for hydrogen-based array constructors 
CacheInitialJSArrayMaps needs to be able to pick up where it left off,
as it can now be called from a handlfied context.

Disable incremental marking for CCTest SetJitCodeEventHandler, as it allocates
during compilation.

885fd2f4b2 Fix yield inside with 
This patch makes it so that suspending generators always saves the
context.  Previously we erroneously assumed that if the operand stack
was empty, that the context would be unchanged, but that is not the case
with "with".

Fixing this brought out an interesting bug in the variable allocator.
Yield inside with will reference a context-allocated temporary holding
the generator object.  Before the fix, this object was looked up in the
with context instead of the function context, because with contexts were
not being simulated during full-codegen.  Previously this was OK as all
variables would be given LOOKUP allocation instead of CONTEXT, but the
context-allocated temporary invalidated this assumption.  The fix is to
simulate the context chain more accurately in full-codegen.

7b2abd7c1e MIPS: Capture receiver in generator object 
Port r14434 (04f254d1)

Original commit message:
Previously there has been no reason to context-allocate the receiver, so
access to the receiver always goes through the stack.  This was failing
with generators, which assumed that forcing context allocation would
relieve the need of storing anything but the context and the function on
the stack.

This CL adds a slot in generator objects to capture the receiver, and
restores it when resuming a generator.

7ed7af2f9f Tell the GC prologues to construct RetainedObjectInfos only when needed. 
The GC prologue is called by the GC, but also by the heap snapshotter. The
RetainedObjectInfos are only needed by the heap snapshotter, so it's wasteful to
construct them always. (And it will be even more wasteful when Blink migrates to
the new GC APIs, since after that point it no longer knows about object groups.)
