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

I had a look through this and everything seemed to be in place. I think the ABI versioning is probably sufficient to prevent surprises and land this now, to avoid churn in the rest of the code. If more is really needed, we could add a temporary warning ("incomplete ABI") to the Clang driver.
