Reland "Turn ElementsTransitionAndStore stub into a HydrogenCodeStub".
...
Fix the invalid array length check, replacing it with a check of
the elements pointer similar to TransitionElementsKindStub.
Refactor common code from ElementsTransitionAndStoreStub and TransitionElementsKindStub into BuildTransitionElementsKind() helper method.
Add test case for the MD5 computation that used to crash before,
and a small test case for the specific issue.

Reland deprecation of HAllocateObject in favor of HAllocate.
...
This essentially relands r14930 and r14935 with adaptions to the current
code base. It models the instantiation of an implicit receiver for
CallNew nodes in hydrogen using HAllocate together with generic stores
instead of one specialized HAllocateObject instruction, hence creating a
single choking point for inlined allocation in optimized code.
