Follow-up to 14951a5a3120e50084b3c5fb217e2d47992a24d1 * Unify getVariantKindName and getVariantKindForName * Allow each target to specify the preferred case (albeit ignored in MCParser) Note: targets that use variant kinds should call MCExpr::print with a non-null MAI to print variant kinds. operator<< passes a nullptr to `MCExpr::print`, which should be avoided (e.g. Hexagon; fixed in commit cf00ac81ac049cddb80aec1d6d88b8fab4f209e8).
