> Since this is compilinga statement returning the specific node makes more sense and will
lead to a little more clarity in the code.
> Some of the methods defined on QueryTreeNode such as generate() and needsSavepoint()
can move down to StatementNode and thus make the code more readable ("which generate is called
for a value node?") and remove implementations of these methods that can never be called.
