I wondered who those callers might be, too, because it is such a weird
thing for a caller to want to care about (usually we try to abstract the
object database).
It looks like the only user went away in 97b2fa08b6 (fetch-pack: drop
custom loose object cache, 2018-11-12). So I think we just want to drop
it:

We could also renumber the later flags to keep them compact, but I don't
have a strong opinion there.
