      Description

      It's not valid to simplify FLOOR(CEIL(x)) to FLOOR(x).

      Specifically, it is not valid to simplify FLOOR(CEIL(x TO YEAR) TO YEAR) to FLOOR(x TO YEAR) when x is TIMESTAMP '2010-10-10 00:00:00'. I believe the correct simplification is CEIL(x TO YEAR).

      I have disabled RexImplicationCheckerTest.testSimplifyFloor due to this issue. Please re-enable it as part of the fix for this bug.
