Comment:
I believe this is required for mesa to work correctly with the new rx 7000s series amd GPU's. So to make them plug ń play we'll need to both merge this and swap the depedency in `mesa` from `llvm` to `llvm15`. 

FWIW; merging this branch into #41084 and changing #41084 to `llvm15` worked for me, but I also needed to fetch the latest `linux-firmware-amd` blobs, update `SPIRV-{Headers,LLVM-Translator}`, hack some stuff into `shlibs` which I'm not familiar with.
