Igor Babaev abc123391f Fixed mdev-6706 Wrong result (missing rows) ...

with joins, SQ, ORDER BY, semijoin=on

A bug in get_sort_by_table() could mislead the function
setup_semijoin_dups_elimination(). As a result the optimizer
could produce invalid execution plans for queries with ORDER BY
and subquery predicates that could be converted to semi-joins.
