We do not have generic a `FeatureGFX1170Insts` as we do for almost every other target, since we have a feature (or are adding a new one) for all instructions that are different from base gfx11/gfx1150. Should we add one?  This predicate is tied to the generation of _gfx1170 `Real`s same as for every other generation.
