Need to update mappings in TrackedToOrig to correctly provide mapping between updated reduced value after vectorization and its original value, otherwise the compiler might miss this update and it may cause compiler crash later, when it tries to find the original instruction mapping for the updated value. Fixes https://github.com/llvm/llvm-project/issues/109376
