[Dwarf-Discuss] Split Dwarf vs. CU DW_AT_ranges / DW_AT_low_pc placement

Hopefully not to side-track things too much... maybe wants its own
thread, if there's more to debate here.

Did you want to file an issue to improve how .debug_aranges works?

Complaining that it duplicates CU ranges is missing the point, though;
it's an index, like .debug_names, of course it duplicates other info.
If you want to suggest an improved index, like we did with .debug_names,
that would be great too.
