OK -- I'd be glad to do that. Could you possibly
provide me an example to work from?
arm_scan_prologue is easy, since it accepts prologue instructions
in any order, but arm_skip_prologue imposes an ordering on them.
I would REALLY like to merge these two functions. In fact I started
to, but then got busy with other things.
