d3d77f71 - [EarlyCSE,TTI] Don't create new, unused, instructions. (#134534)

[EarlyCSE,TTI] Don't create new, unused, instructions. (#134534) getOrCreateResultFromMemIntrinsic can modify the current function by inserting new instructions without EarlyCSE keeping track of the changes. Introduce a new CanCreate argument, and update the function to only create new instructions when CanCreate = true. Use it when appropriate. Fixes https://github.com/llvm/llvm-project/issues/145183
