> AggregateJoinTransposeRule currently only fires if the Aggregate has no aggregate functions. We need to lift that limitation.
> Aggregate functions should be split, e.g. COUNT becomes SUM of COUNT. Some aggregate functions cannot be split, e.g. distinct-count.
> Add a new interface to SqlAggFunction to allow it to declare the split policy.
