ARM64: hexify printing various immediate operands

This is mostly aimed at the NEON logical operations and MOVI/MVNI (since they
accept weird shifts which are more naturally understandable in hex notation).

Also changes BRK/HINT etc, which is probably a neutral change, but easier than
the alternative.
