ARM64 supports storing pointer authentication codes in the upper bits of
a pointer. This mask can be used by LLDB to mimic ptrauth_strip and
strip the pointer authentication codes. To recover an address from
pointer with an authentication code, `AND` this mask with the pointer.
If the platform does not support pointer authentication, or the range of
valid addressees for a pointer was unaccessible, this field will be 0
and should be ignored.
