Thanks Mark!
This, indeed, is going to be useful for libabigail at least. This new
dwarf_cu_getdwarf function, along with the existing dwarf_diecu function
will allow us to get the actual Dwarf a given DIE comes from. And with
the recently added dwarf_getalt function, we'll be able to tel if the
DIE comes from the alternate Dwarf or not. This is awesome.
Thanks again.
Cheers.
