This is just for the archives. I was looking at some other dwarf
information that could be compressed. There was a proposal from Jim
Blandy a long time ago on denser dwarf macro information
(the .debug_macinfo sections).

As far as I can see this idea was never implemented. I don't know why
though. Maybe a simpler approach that just gets the strings shared is
more effective? Same seems to be true for .debug_line, which also
doesn't reference strings through .debug_str. Is that a good or bad
idea?
