Sorry, I haven't closely followed the AArch64 PAuth work. The Clang driver 
options should come last in the patch stack, with other patches reviewed first.

For driver options, I don't know a bunch of `-fptrauth-*` is a good idea. We 
had a similar scenario with -mbranches-within-32B-boundaries (an umbrella 
option): the individual options are essentially never used. Have you thought 
about `-fptrauth-something=call,return,indirect-goto`?
