Remove useless "rough estimate" path from mcelem_array_contained_selec.
The code in this function that tried to cope with a missing count histogram
was quite ineffective for anything except a perfectly flat distribution.
Furthermore, since we were already punting for missing MCELEM slot, it's
rather useless to sweat over missing DECHIST: there are no cases where
ANALYZE will create the first but not the second. So just simplify the
code by punting rather than pretending we can do something useful.
