IMPALA-5689: Avoid inverting non-equi left joins

When checking if a join can be inverted, we forgot to also check that
the resulting join would not be a non-equi right semi-join or a
non-equi right outer-join. We currently do not support those kinds of
joins in the backend.

Testing:
-Added a planner test
