* include/abg-fwd.h (node_visitor_base): Renamed ir_node_visitor into this. * include/abg-traverse.h (struct node_visitor_base): New base for the visitors. (struct traversable_base): Update comments. (traversable_base::traverse): Change this into non-pure virtual. Make it take a reference to node_visitor_base, rather than a reference to ir_node_visitor. * src/abg-traverse.cc (traversable_base::traverse): New empty default implementation. * include/abg-ir.h: Make ir_node_visitor inherit from new node_visitor_base.
