[PATCH v3 0/8] Correctly handle inline functions with dwz

The new indexer does not correctly handle inline functions when 'dwz'
is used to compress the DWARF. This series fixes the bug, cleaning up
a number of other things on the way.

I've separately regression tested each patch in this series on x86-64
Fedora 41. I've also regression tested the series as a whole with the
dwz, gdb-index, and debug-names boards.

Even with that I messed up somehow, so v1 didn't actually fix the bug
in question. I must have modified the patches after testing..?

Anyway in v2 I've moved the line recording the CU inclusion and added
a comment explaining the placement. I re-ran the aformentioned tests
and didn't touch anything.
