  Log Message:
  -----------
  [arm64e] Add a builtin + intrinsic for arm64e PAuth_LR: __builtin_ptr_auth_auth_with_pc_and_resign (#202742)

The new builtin behaves like __builtin_ptrauth_auth_and_resign, but
incorporates the address of the signing instruction (i.e. the
`pacibsppc`/`paciasppc`) when performing the auth side, and subsequently
re-signs using a different scheme. Authenticating the re-signed value
will fail if and only if authenticating the original value with the
incorporated pc would have failed.
