End goal is to update MemorySSA from LoopUnswitch, which clones all blocks in a loop.
This is a **DRAFT** API based on what I found needed in the old LoopUnswitch pass.
Asking for feedback on what parts (I have guessed) these additions are duplicating, and how to simplify.
Adding dependent patches using this API for context.
