I don't need any buildfarm changes for that.
Shortly I'll do the back-patch of LLVM 14 API changes (their final release tag is scheduled for tomorrow, as I've been reminded by package maintainers trying and failing to build). But I figured I should also follow up on this bandaid solution to the API deprecation warnings, that is, silencing them for now, so we don't spew screeds of warnings. Does someone have a better idea than the attached?

We are going to need to handle the opaque pointer API changes[1], possibly in time for LLVM 15, but in the meantime let's silence the warnings produced by LLVM 14.
