Description:

    PR22187, infinite loop in find_abstract_instance_name

    This patch prevents the simple case of infinite recursion in
    find_abstract_instance_name by ensuring that the attributes being
    processed are not the same as the previous call.

    The patch also does a little cleanup, and leaves in place some changes
    to the nested_funcs array that I made when I wrongly thought looping
    might occur in scan_unit_for_symbols.

        PR 22187
        * dwarf2.c (find_abstract_instance_name): Add orig_info_ptr and
        pname param.  Return status.  Make name const.  Don't abort,
        return an error.  Formatting.  Exit if current info_ptr matches
        orig_info_ptr.  Update callers.
        (scan_unit_for_symbols): Start at nesting_level of zero.  Make
        nested_funcs an array of structs for extensibility.  Formatting.

Affects: <= 2.29
