[SPARK-17244] Catalyst should not pushdown non-deterministic join conditions ## What changes were proposed in this pull request? Given that non-deterministic expressions can be stateful, pushing them down the query plan during the optimization phase can cause incorrect behavior. This patch fixes that issue by explicitly disabling that. ## How was this patch tested? A new test in `FilterPushdownSuite` that checks catalyst behavior for both deterministic and non-deterministic join conditions.
