So this parses objdump output, and we also already have the annotation
logic that does that too, have you thought about having common routines
for these two cases?

I mean the disasm_line, ins, ins_ops, ins_operands classes, that now
lives in util/annotate.h but could be moved somewhere else,
disconnecting it as much as possible from annotation, because probably
there are more cool things we could do with that... :-)

We could certainly do it incrementally, merging your current patch
series and then working on sharing code on these two use cases, but
perhaps you can do it now?

What do you think?
