  1. sql/parser: Verify that AggregateFuncs deep copy Datums on Result 

    This makes sure that all Datums returned from the Result method of
AggregateFunc implementations are deep copies of any internal state.
This is necessary to allow for ordered window functions that will
incrementally call Result on an aggregate, and expect each resultant
Datum to be a separate deep copy and not modified on future
accumulation.
