> Remove vectorization related constant expression folding code once Constant

> 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().
