The other option is to change how intrinsics work on x86 and use resolve
overloads inside the backend like how aarch64, arm and rs6000 backends all
handle intrinsics these days.
That would be a huge rewrite of the intrinsics but it might resolve some of the
other issues dealing the builtins and such too.
