Is the format of these "compact unwind tables" described somewhere?
It would be nice if libunwind would work at least as well or better
than the libgcc_s unwinder, so if it's reasonably possible, it would
be nice to add support for these compact tables.

I'll review the complete patch in the next few days.  I'm actually
quite interested in the ARM support as it will help me with a little
embedded project of mine, so thanks! ;-)
