Igor Babaev cff60be7fe MDEV-15899 Server crashes in st_join_table::is_inner_table_of_outer_join 
The crash happened because JOIN::check_for_splittable_materialized()
called by mistake the function JOIN_TAB::is_inner_table_of_outer_join()
instead of the function TABLE_LIST::is_inner_table_of_outer_join().
The former cannot be called before the call of make_outerjoin_info().
