Increasing address pool reuse/reducing .o file size in DWARFv5
...So, I've brought this up a few times before - that DWARFv5 does a pretty
good job of reducing relocations (& reducing .o file size with Split DWARF)
by allowing many uses of addresses to include some kind of address+offset
(debug_rnglists and loclists allowing "base_address" then offset_pairs (an
improvement over similar functionality in DWARFv4 because the offset pairs
can be uleb encoded - so they can be quite compact))
But one place that DWARFv5 misses to reduce relocations further is direct
addresses from debug_info, such as DW_AT_low_pc.
For a while I've wondered if we could...
