> I think moving VFP4 check into the useFPVMLx method would help make this easier to read.

Thanks for the suggestion. I had a look, and turns out we don't need it at all because the VFP checks and predicates are already on the rules. Thus we can simplify the UseFPVMLx predicate even more by removing the VFP check from it.
