IMPALA-5689: Avoid inverting non-equi right joins

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

Testing:
-Added a planner test
