[SPARK-21652][SQL] Fix rule confliction between InferFiltersFromConstraints and ConstantPropagation ## What changes were proposed in this pull request? For the given example below, the predicate added by `InferFiltersFromConstraints` is folded by `ConstantPropagation` later, this leads to unconverged optimize iteration: ``` Seq((1, 1)).toDF("col1", "col2").createOrReplaceTempView("t1") Seq(1, 2).toDF("col").createOrReplaceTempView("t2") sql("SELECT * FROM t1, t2 WHERE t1.col1 = 1 AND 1 = t1.col2 AND t1.col1 = t2.col AND t1.col2 = t2.col") ``` We can fix this by adjusting the indent of the optimize rules. ## How was this patch tested? Add test case that would have failed in `SQLQuerySuite`.
