Fixed bug mdev-12099.
The function mysql_derived_merge() erroneously did not mark newly formed
AND formulas in ON conditions with the flag abort_on_null. As a result
not_null_tables() calculated incorrectly for these conditions. This
could prevent conversion of embedded outer joins into inner joins.
Changed a test case from table_elim.test to preserve the former execution
plan.
