Varun Gupta ddc5c65333 MDEV-14779: using left join causes incorrect results with materialization and derived tables ...

Conversion of a subquery to a semi-join is blocked when we have an
IN subquery predicate in the on_expr of an outer join. Currently this
scenario is handled but the cases when an IN subquery predicate is wrapped
inside a Item_in_optimizer item then this blocking is not done.
