Can you add a RISC-V test? We've had lots of problem w/ target features in LTO w/ RV, and we've done a few things to try and mitigate that by plumbing them through the backend. I'd like to know how this patch ends up interacting w/ that, and whether this solve some of the remaining issues, or if we need further triage for that backend.

#50591, https://github.com/llvm/llvm-project/issues/65090, https://github.com/llvm/llvm-project/issues/69780 are all related to some extent.
