Please add some information about other approaches you considered/attempted to solve this problem. I really don't like the idea of doing store forwarding in the peephole. Are there no existing passes that can perform this type of store forwarding (and most likely more general forms of it)? While I am not all that familiar with `MemorySSA`, it would seem that this is the exact type of thing it should handle effortlessly.
