ac/nir: Add vote_ieq/vote_feq lowering pass. The old vote_eq implementation supported only booleans, but now we have to support arbitrary values, so use the read_first_invocation intrinsic + ballot. I took this as an opportunity to figure out how easy it was to do this in nir instead of in the nir_to_llvm pass, and it actually turned out pretty okay IMO. Only creating the pass is some extra code. Reviewed-by: Dave Airlie <airlied@redhat.com>
