improve default indexing for objects * ov-class.cc (octave_class::is_class_method): Also return true for anonymous functions executing in the context of a class method or constructor. * ov-class.h (octave_class:do_multi_index_op): New function. * ov-fcn.h (octave_function::is_private_function_of_class): Now const. (octave_function::is_anonymous_function_of_class): New virtual function. * ov-usr-fcn.h (octave_function::anonymous_function): New data member. (octave_user_function::mark_as_anonymous_function): New function. (octave_user_function::is_anonymous_function): New function. (octave_user_function::is_anonymous_function_of_class): New function. * ov-usr-fcn.cc (octave_user_function::octave_user_function): Initialize anonymous_function data member. (octave_user_function::profiler_name): Distinguish between inline and anonymous functions. (octave_user_function::do_multi_index_op): Use is_anonymous_function instead of checking whether cmd_list is marked as an anonymous function body. * pt-fcn-handle.cc (tree_anon_fcn_handle::rvalue1): If parent function is a class method or constructor, stash the dispatch type in the new function. Mark the new function as anonymous, not inline.
