    Handle nodes that may appear in GraphPattern expression trees
    
    expression_tree_mutator_impl() did not handle T_GraphPattern,
    T_GraphElementPattern, and T_GraphPropertyRef.  The corresponding
    expression_tree_walker_impl() already handles all three node types.
    This causes an "unrecognized node type" error whenever a GRAPH_TABLE
    appeared in an expression tree.
    
    While at it, also update raw_expression_tree_walker() and
    expression_tree_walker() to handle missing nodes that may appear in
    GraphPattern expression trees.  When raw_expression_tree_walker() is
    called, GraphElementPattern::labelexpr contains ColumnRefs instead of
    GraphLabelRefs.  Hence those are not handled in
    raw_expression_tree_walker().
