Do not eagerly finalize classes in CHA, instead regard unfinalized classes as ’non-existent’ and only invalidate optimized code at finalization of the class.
...
Rename FinalizePendingClasses to FinalizePendingClassInterfaces as the class finalization occurs lazily.
TODO: add dependency information to deoptimize/remove only relevant optimized code.

VM: Fix CHA for Object.
...
Class hierarchy analysis does not track subclasses of Object.
Therefore, it needs to safely assume that any functions has an override.
This fixes test failures when running with --optimization-counter-threshold=5.

Added macros OBJECT_IMPLEMENTATION and FINAL_OBJECT_IMPLEMENTATION
...
which have different implementations of 'operator=' and 'operator^='.
In the case of FINAL_OBJECT_IMPLEMENTATION we do not do the vtable setting
in these methods (Note the |= operator functionality is now subsumed into
the new implementation of "operator^=")

Do not recompute unary_checks repeatedly. Add special (and quicker) way to check for method overrides using CHA.

Use kInstanceCid instead of object_store()->object_class() when checking to see if the class is object class.
