[PATCH 2/2] libctf: impose an ordering on conflicting types

[Nick Alcock]

On 27 Apr 2022, Nick Alcock via Binutils verbalised:

> When two types conflict and they are not types which can have forwards
> (say, two arrays of different sizes with the same name in two different
> TUs) the CTF deduplicator uses a popularity contest to decide what to
> do: the type cited by the most other types ends up put into the shared
> dict, while the others are relegated to per-CU child dicts.

(Installed. Original reporter says it fixes his bug -- internal or
there'd be a sourceware bug. Maybe I should ask for one in future
from internal reporters anyway, since it's user-visible?)
