[Patch v12 3/4] Add support for lookup, overload resolution and invocation of C++ debug methods

[Siva Chandra <sivachandra at google dot com>]

This part uses the debug method extension language API to lookup,
perform overload resolution, and invoke debug methods of C++ classes.

Doug had a comment about a call to invoke_debug_method:

Siva> +    ret_val = invoke_debug_method (dm_worker, arg2, argvec + 2,
Siva> +                                                     nargs - 1);

Doug> Can invoke_debug_method throw an error?
Doug> [One could use a cleanup to free dm_worker, regardless.]

Yes, invoke_debug_method can throw an error.  You are probably
pointing out a memory leak here when an error is thrown.  While I did
not address this possibility, how would a cleanup help here?

        defined in extension languages.
        * valarith.c (value_x_binop, value_x_unop): Lookup and invoke
        overloaded operator methods defined in extension languages.
        * valops.c (find_oload_method_list, find_method_list,
        find_overload_match, find_oload_champ): Lookup methods defined
        in extension languages.
