This code was already creating HandleSDNodes to handle the case where a node gets replaced with an equivalent node. However, the code before the handles are created also performs RAUW operations, which can end up CSEing and deleting nodes. Fix this issue by moving the handle creation earlier. Fixes https://github.com/llvm/llvm-project/issues/160040.
