ValueNode
ValueNode.isEquivalent(org.apache.derby.impl.sql.compile.ValueNode)
cannot always just use instanceof
to check if the other node
represents the same kind. Hence this method needs to be
overridden by all node classes that represent several kinds.
This default implementation does not look at kinds.
It is only called from implementations of isEquivalent
