What are the rules for using an aarch prefix instead of an arm prefix?
I haven't talked to Kinsey about this but I would assume based on the
terminology I see in ARM documentation.
+ arm - only 32-bit. Now referred to as aarch32 or A32
+ aarch64 - only 64-bit. AKA A64
+ aarch - shared across 32 and 64 bit modes.
Looks like Microsoft also uses ARM32 and ARM64
Linux uses "arm" and "arm64". You find some aarch32 stuff in
"arch/arm64" but not in "arch/arm". I think we should do the same.
Existing and shared stuff between "arm" and "aarch64" should just use "arm".
