Erik, thanks for working on this. You're reusing the DWARFDebugFrame
class, but AFAIK there are subtle format differences between
.debug_frame and .eh_frame. E.g. check out this:
http://www.airs.com/blog/archives/460 and other resources.

Thoughts?

Also, I'm concerned about your test not being restricted to a specific
architecture/triple. It may fail on platforms with different word size
and other parameters. Where did you test it?

P.S. I'm going out to send a patch to enhance DWARFDebugFrame with
some initial CFA instruction parsing very soon. It shouldn't interfere
with yours, though.
