IMPALA-13576: Fix filter placement in the plan and related changes.
This patch combines the following changes:
- Filter above a Sort RelNode is now supported (IMPALA-13576)
- A new rule is added to remove empty sort keys, as in the example
SELECT '1' FROM alltypestiny ORDER BY 1
This also required bumping up the Calcite version to 1.37. (IMPALA-13578)
- A parser fix to allow LIMIT clause in a subquery (IMPALA-13579)
- Added optimization to push Filter past the Project RelNode (IMPALA-13577)
This optimization needs to be added before "CoerceNodes" so that the filter
does not get passed through a generated Project RelNode created for handling
conversion of Calcite literal types to Impala literal types (see
ImpalaProjectRel.isCoercedProjectForValues() method for details on that).
