This is a follow-up for https://github.com/llvm/llvm-project/pull/119110
and a fix for https://github.com/llvm/llvm-project/issues/118450
RemoveDeadValues used to delete Values and analyzing the IR at the same
time, because of that, `isMemoryEffectFree` got invalid IR with
half-deleted linalg.generic operation. This PR separates analysis and
cleanup to prevent such situation.
Thank you!
