e3e7daf01c We need to know if a load, store or call IC is assumed
to be on the global object. Previously, this information
was stored in RelocInfo. A more logical place for this kind
of structural information is ExtraICState. Storing it there
makes it easier for us to gather type feedback from these
sites too.

5567426483 Do not put allocated block into HeapObjectsMap
Heap allocation reported to AllocationTracker may be later divided into several objects so it is incorrect to put the block as a new HeapObject into the map. We will match allocated block with actual HeapObjects later when iterating Heap (will be addressed in another patch). Since the objects are not assigned an id immediately after creation we need to call FindOrAddEntry when finding id for SharedFunctionInfo during stack crawling.

Removed hooks for tracking creation of AllocationMemento. AllocationMemento is not a HeapObject and should be considered as implementation overhead.

Renamed NewObjectEvent to AllocationEvent which is more precise in case of folded allocations and when a part of the new block becomes AllocationMemento.

e066a3667d Move responsibility for definition of ExtraICState bits into the ICs.
Currently it's in the Code object for some ICs and in ICs for other ICs.
This should make it easier to alter bits as needed.

2) Recover an extra bit in the code object to give us 6 bits for the extra ic state. We'll need it soon to store contextual state.

3) Cleanup code that treated StrictMode enum and ExtraICState enum as interchangeble.

adae3f77ec Allow redirecting disassembly and deoptimization traces into a file.
This is controlled by two flags:

--redirect_code_traces
--redirect_code_traces_to=<filename>

When redirection is enabled but --redirect_code_traces_to is not specified traces are written to a file code-<pid>-<isolate>.asm. This mangling scheme matches hydrogen.cfg and allows easy discovery of compilation artifacts in a multi-V8 environment (e.g. when compilation is traced from inside Chromium).

D8 defines --redirect_code_traces_to=code.asm similar to hydrogen.cfg redirection.

709012021a The compiled_transitions flag was enabled for quite some time now and seems to work out quite well, so time has come to remove the obsolete code paths and remove the unused methods.

ec8c6f4692 Rename AllocationSiteInfo to AllocationMemento
This is just a rename change with the exception of a bug found along the way in
CodeStubGraphBuilder<FastCloneShallowArrayStub>::BuildCodeStub(). There, the
intent is to get the boilerplate object from an AllocationSite. But the wrong
HObjectAccess was used. It only succeeds because it happened to be the same
offset :).
