Thanks, I've gone through the list and removed all not-ARM
instructions, and added some missing ARM branch instructions:

Ideally ARM would - like this powerpc implementation - add a
ins__find_arm() to handle its condition codes, but, for now, is
it possible to merge this change into this series? I can post a
follow-up patch if not.
