> 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().
