This is something that we've talked about for quite some time,
having separate "max" cpu types for Armv{8,9}, because Armv9
prohibits some deprecated Armv8 features.  Retaining all features
simultaneously has the potential to cause confusion.

Changes for v3:
  - Several patches merged.
  - max-v8 is also present for qemu-{system-}arm.

I realize the registration of -cpu max-v8 will need adjustment
for single-binary, but in the short term I've used an ifdef.
