However, some of the users might be fr= eed 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. This fixes a possible crash when building crypto/openssh/sshkey.c for PowerPC targets.
