  Log Message:
  -----------
  [clang] Add support for `__ptrauth` being applied to integer types (#137580)

Allows the __ptrauth qualifier to be applied to pointer sized integer types,
updates Sema to ensure trivially copyable, etc correctly handle address
discriminated integers, and updates codegen to perform authentication
around arithmetic on the types.
