A general hook is the "char* disassembler_options" field, which is used
as a catch-all.  Where this field is used (arm, i386, ppc), it's almost
exclusively to encode the ISA selection.  I'd prefer to formalize the
isa switch than continue to deformalize to a string option, especially
as isa switching is a correctness issue.  (Some of these disassembleres
use the string also for rendering preferences.)

OK.  Anyone with objections?
