> See HIVE-511 for an example of the move.
> size, if, isnull, isnotnull are all implemented with UDF but they are 
> actually working on variable types of objects. We should move them to 
> GenericUDF for better type handling.
> This also helps to clean up the hack in doing type matching/type conversion 
> in UDF.
