[PATCH] D75594: [AArch64] Add support for Fujitsu A64FX

Looks good, I agree with @dmgreen that a clang driver test would be nice.

I think AEK_DOTPROD was introduced with 8.4 (and backported to 8.2 as an optional feature?) so I suspect the dot product support is just for SVE; it certainly isn't present in the cpuinfo feature flags.

As far as the loop alignment goes, would the A64FX benefit from planting an unconditional branch at the start of a series of alignment nops to skip actually executing them?
