Yeah.  I have another patch to remove it from end_psymtab_common, but I
didn't look at removing it from the add_psymbol methods.

I think it's a good idea, but it might be a pain to pipe the object
everywhere it is needed.  So I'd prefer to do this as a separate patch.

I feel like the stats are not very useful and could just be removed.  I
have never once used them; the bcache already tracks its own efficiency;
and gdb already knows how many psymbols actually exist.
