I couldn't find a clean way to wire in `RuntimeLibcallsInfo::getFunctionTy` here to add the NonLazyBind fn attribute for non-arm64e targets. Given there are no other target checks in this file, I do want to move it, but since `lowerObjCCall` doesn't have a `RuntimeLibcallsInfo` instance I was wondering if you had an approach in mind that I should implement?
