The current pattern does not match a ')' inside the argument list. This will no longer work because `nocapture` became `captures(none) in 29441e4f5fa5f5c7709f7cf180815ba97f611297 (llvm-project). Use a wildcard regex instead. Doing so does not compromise the test because the `unnamed_addr` attribute we are guarding against can appear only after the argument list. This is intended to reduce future conflicts with rebranch.
