    Change ARI to mention C++11, and remove some rules
    
    I noticed that ARI mentions "ISO C 90", but now gdb uses C++11.  This
    patch updates some text to reflect this change.
    
    I also noticed that a few rules can be removed now.  ARGSUSED doesn't
    seem to be an issue any more (there's no code mentioning this and I
    doubt most of us even remember this convention); PARAMS was specific
    to K&R C; and __func__ is available in C++11.
