In #88846 I changed this code to use RAUW to perform the replacement instead of manual updates -- but kept the outer loop, which means we try to perform RAUW once per user. However, some of the users might be freed by the RAUW operation, resulting in use-after-free. The case where this happens is constant users where the replacement might result in the destruction of the original constant. Fixes https://github.com/llvm/llvm-project/issues/92991.
