I think that this should go under `#if
__has_extension(ptrauth_restricted_intptr_qualifier)` (just like in other
places touched by this PR, see libunwind.h for example). As far as I can see,
`__ptrauth_restricted_intptr` is not yet supported by mainline, and using that
causes compile errors on my side.
