Misc; Was: [RFA]: x86_64 target files

[Andrew Cagney <ac131313@cygnus.com>]

Jiri, some quick comments on things that caught my eye.  Once the 
*-tdep.c file is multi-arched (as much as possible) I'll go review the 
*-nat file properly.

	enjoy,

You are encouraged to create a file like:

	x86_64-tdep.h

so that this sort of thing can be shared amonst the various x86_64 
specific files.  Both *-nat and *-nat-linux contained that exact table. 
  Just be careful to namespace proof things a little (x86_64 prefixes 
and the like).

Have a look at the ARM which queries opcodes for a list of disassembly 
variants instead of duplicating those variants here.

FYI, I don't think that the code stream stuff belongs in a *-tdep.c. 
Hmm, I suspect you accidently picked it up when clonning i386-tdep.c. 
Could I recommend going through your new *-tdep.c file and cleaning out 
anything that isn't being used.
