i386 flavors [Was: Re: Misc; Was: [RFA]: x86_64 target files]

[Andreas Jaeger <aj at suse dot de>]

Here's a proposal for an implementation  - it's similar to the arm way
of doing it.

I would additionally export print_insn_i386 and then gdb would use
that call.  i386-tdep.c and x86-64-tdep.c would need to use the new
interface, I can send patches if we like to go this way.

Mark, as i386 maintainer, what do you think?
