* include/abg-ir.h (ir_traversable_base): New type to be the base of IR nodes that are to be traversed. Extends traversable_base. Its ir_traversable_base::traversable() method takes an ir_node_visitor&. (ir_node_visitor::visit): Change these virtual overloads to take pointers to IR nodes, rather than references. This will be useful to e.g, store these IR nodes in containers on the side for some algorithms to work. That is going to be useful later to, e.g. build symbol tables on the side, using the visitor interface. (class decl_base): Make this inherit ir_traversable_base. * src/abg-ir.cc (*::traverse): Adjust comments and the call the ir_node_visitor::visit call. Use the ir_traversable_base type rather than traversable_base. (ir_traversable_base::traverse): Define. (ir_node_visitor::visit): Change these overloads to take pointers rather than reference to ir nodes. * tests/test-walker.cc (name_printing_visitor::visit): Adjust to take pointers rather than references.
