        Fixed using the Objective-C 2.0 syntax with self and super.
        * objc-act.c (OBJC_LOOKUP_NO_INSTANCE_METHODS_OF_ROOT_CLASS): New.
        (maybe_make_artificial_property_decl): Added 'implementation'
        argument.  Use OBJC_LOOKUP_NO_INSTANCE_METHODS_OF_ROOT_CLASS when
        looking up getters or setters for a class.  If an implementation
        is specified, search it as well for a getter or setter.
        (objc_maybe_build_component_ref): Updated calls to
        maybe_make_artificial_property_decl; added code to deal with
        'self' and 'super' and with methods declared locally in the
        implementation.  Store the getter call expression in the
        PROPERTY_REF instead of throwing it away.
        (objc_build_class_component_ref): Updated calls to
        maybe_make_artificial_property_decl, and store the getter call
        expression in PROPERTY_REF instead of throwing it away.
        (lookup_method_static): Implemented
        OBJC_LOOKUP_NO_INSTANCE_METHODS_OF_ROOT_CLASS option.
        (objc_gimplify_property_ref): Do not build the getter method call
        here; instead use the one stored in the PROPERTY_REF.  If it's not
        there, produce helpful error messages.
        * objc-tree.def (PROPERTY_REF): Increased the number of operands
        from 2 to 3.  Updated comments.
        * objc-act.h (PROPERTY_REF_GETTER_CALL): New.
