      Description

      When there are multiple predicates in RexSimplify, only the first predicates will be used to simplify the RexNode. The following test can reproduce.

      // RexProgramTest.java
      @Test public void testSimplifyRangeWithMultiPredicates() {
        final RexNode ref = input(tInt(), 0);
        RelOptPredicateList relOptPredicateList = RelOptPredicateList.of(rexBuilder,
            ImmutableList.of(gt(ref, literal(1)), le(ref, literal(5))));
        checkSimplifyFilter(gt(ref, literal(9)), relOptPredicateList, "false");
      }
