Summary: When using MemorySSA, re-optimize MemoryPhis when removing a store since this may create MemoryPhis with all identical arguments. Also, when using MemorySSA to check if two MemoryUses are reading from the same version of the heap, use the defining access instead of calling getClobberingAccess, since the latter can currently result in many more AA calls. Once the MemorySSA use optimization tracking changes are done, we can remove this limitation, which should result in more loads being CSE'd.
