Go with dwarf2 unwinders.  That's a much more efficient implementation and
it doesn't unduly restrict code generation.  That's the long term plan for
most platforms.  It just needs someone to spend the time to make it work
for the PA.

On a similar note it would be good if someone switched the PA32 port from
using embedded stabs to dwarf2 debug info.
