> HIVE-5771 covers Constant propagation optimizer for Hive. Now that HIVE-5771 
> is committed, we should remove any vectorization related code which 
> duplicates this feature. For example, a fn to be cleaned is 
> VectorizarionContext::foldConstantsForUnaryExprs(). In addition to this 
> change, constant propagation should kick in when vectorization is enabled. 
> i.e. we need to lift the HIVE_VECTORIZATION_ENABLED restriction inside 
> ConstantPropagate::transform().
