It is adding new CPU support to clang 18, specifically the ampere-1b. I'm not
sure what is considered acceptable at this stage. It is up to the release
maintainers whether they want to accept it. On a technical level I believe it
should be OK, but if only regressions are being fixed at this stage then it
might be better to wait for clang-19. I'm not sure how much @ptomsich wanted to
get this into clang-18?
