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.
