Subject: [PATCH] BUG#869012: Wrong result with semijoin + materialization +
 AND in WHERE - in make_join_select(), use the correct condition to check
 whether the current table is a SJM nest (the previous   condition used to be
 correct before, but then sj-materialization temp table creation was moved to
 happen before   make_join_select was called)
