        * objc-act.c (OBJC_GEN_METHOD_LABEL): Updated comments.
        (objc_demangle): Return NULL if demangling can not be done because
        the string to demangle is not an Objective-C mangled method name.
        Be smarter in demangling method names so that at least for methods
        with no arguments we are able to almost always demangle '_' correctly.
        Updated comments.
        (objc_maybe_printable_name): New.
        (objc_printable_name): Call objc_maybe_printable_name.  If it
        returns NULL, call cxx_printable_name in Objective-C++.
