[PATCH] D87095: [Triple][MachO] Define "arm64e", an AArch64 subarch for Pointer Auth.

Hi, thanks for getting started on upstreaming this!

But I was wondering: shouldn't this be the *last* patch? I was imagining that you would first upstream support for the `-fptrauth-*` flags, and then at the end you would add an `arm64e` subarch that turns them on by default. Otherwise the upstream compiler will temporarily produce ABI-incompatible objects when targeting `arm64e`.
