date case.

> The Sargs impl today converts the statsObj to the type of the predicate 
> object before doing any comparisons.
> To satisfy the PPD requirements, the conversion has to be coerced to the type 
> specified in PredicateLeaf.type.
> The type conversions in Hive are standard and have a fixed promotion order.
> Therefore the PredicateLeaf has to do type changes which match the exact 
> order of type coercions offered by the FilterOperator.
