> Allow Complex Types to be vectorized (since HIVE-16207: "Add support for
> Complex Types in Fast SerDe" was committed).
> Add more classes we vectorize AVG in preparation for fully supporting AVG
> GroupBy. In particular, the PARTIAL2 and FINAL groupby modes that take in
> the AVG struct as input. And, add the COMPLETE mode that takes in the
> Original data and produces the Full Aggregation for completeness, so to speak.
