Sorry, I meant the `__ptrauth` qualifiers currently cannot be used as a
top-level qualifier of function parameters.
```
int func1(void * __ptrauth(1, 0, 100) ptr); // error: parameter types may not
be qualified with __ptrauth; type is 'void *__ptrauth(1,0,100)'
int func2(void * __ptrauth(1, 0, 100) * ptr); // OK
```
