Previously, an analytic function that used the same expr in both the 'partition by' and 'order by' clauses, and where the expr meets the criteria for being materialized before the sort, would hit an IllegalStateException due to the expr being inserted into the same ExprSubstitutionMap twice. If the values have already been partitioned on the expr, then all of the values for it in each partition will be the same and also ordering on the expr doesn't change the results. So, the fix is to simply exclude the duplicate expr from the 'order by' while still partitioning on it. Testing: - Added a regression test to PlannerTest.
