    BUG#901506: Crash in TABLE_LIST::print on EXPLAIN EXTENDED · 05e01274

    - Let JTBM optimization code handle the case where the subquery is degenerate and doesn't have a 
      join query plan. Regular materialization would fall back to IN->EXISTS for such cases. Semi-Join
      materialization does not have such option, instead we introduce and use "constant JTBM join tabs".
