I see. Still don't like the default behavior though. How about instead Create a helper in this file.  and check `Intrinsic::isTargetIntrinsic(ID)` if it is true do `TTI->isVectorIntrinsicWithOverloadTypeAtArg`. if it is false do `isVectorIntrinsicWithOverloadTypeAtArg`.

That way TTI isn't check unless we know its a target intrinsic.
