Review comment:
This fixed the SQLQueryTestSuite failure:
https://github.com/apache/spark/pull/29650/checks?check_run_id=1071934445
It is a very complex query, I'm still figuring out how to cover it in a
simplified unit test in `InferFiltersFromConstraintsSuite`.
Other failures are covered by the "Infer all constraints from a chain of
filters" UT.
