More debug info test directories?

Sounds good to me.

Why not call them gdb.dwarf-1 and gdb.dwarf-2?  Oh, because of
the 8.3 uniqueness requirement.  Sigh.

Well, you could re-visit the issue of dwarf-1 support first.  It may be
too early to remove dwarf-1 support, but I think it's okay to not add
any more dwarf-1 tests.  The existing test suite gave, like, 50 ERRORs
and 3500 FAILs the last time I ran it.  And the only dwarf-1 compilers
I know about are Absoft, Diab, and SCO's version of gcc.
