Bug #39656: Behaviour different for agg functions with & without where -

Browse Source 
ONLY_FULL_GROUP_BY

The check for non-aggregated columns in queries with aggregate function, but without
GROUP BY was treating all the parts of the query as if they are in the SELECT list.
Fixed by ignoring the non-aggregated fields in the WHERE clause.

  Bug #39656: ignore the new non-aggregated column refs in a WHERE
  by saving the state so far and then adding only the new values of the other
  parts of the bitmask.
