Ok, I'm still struggling to see why it is best create (possibly) broken IR,
super heroic "but let us build an even more complicated devices like multiple
intrinsics per AS, and also redo how ASCasts work etc." and rely on implicit
knowledge about what happens with `used` and `compiler.used` (ah, because these
are never CodeGen-ed, it's fine to do whatever). What's the actual benefit
here? Why not make it a special global that uses AS 42, since that'd actually
signal it's special, as opposed to Unqual/0, which do the exact contrary. I'm
also struggling to see the backwards compat angle since we do not guarantee
IR-level compat between LLVM versions (yes it frequently works but it's not
guaranteed to).
