    BUG#836507: Crash in setup_sj_materialization_part1() with semijoin+materialization · 28a70509
    Sergey Petrunya authored
    - setup_sj_materialization() code failed to take into account that it can be that 
      the first [in join order ordering] table inside semi-join-materialization nest 
      is also an inner table wrt an outer join (that is embedded in the semi-join).  
      This can happen when all of the tables that are inside the semi-join but not inside
      the outer join are constant.
    - Made a trivial to not assume that table's embedding join nest is the semi-join 
      nest: instead, walk up the outer join nests until we reach the semi-join nest.
