delocate: handle Aarch64 assembly in parser.

Aarch64 assembly is quite different from x86-64 or POWER. But the system
of directives is the same so there's quite a lot of utility from being
able to use the same delocate framework.

Unfortunately, with peg, there's no obvious way to be able to parse
instructions differently without breaking the parsing into two stages.
Thus the parser is extended here to support all three ISAs. This seems
to work ok without breaking either of the other two.
