  Changed paths:
    M compiler-rt/lib/sanitizer_common/sanitizer_ptrauth.h

  Log Message:
  -----------
  Normalize ptrauth handling in sanitizer runtime:
 1. Include ptrauth.h if ptrauth_intrinsics language feature is specified
    (per ptrauth spec, this is what enables ptrauh.h usage)
 2. For PAC-RET fallback implement two changes:
   - Switch to macro, so we can ignore key argument
   - Ensure the unsigned value is erased from LR, so the
     possibility of gadget reuse is reduced.

Fixes #100467
