Implemented format and noreturn attributes for Objective-C methods.
* objc-act.c (objc_start_method_definition): If method attributes
are specified emit a warning and ignore them.
(build_objc_method_call): Moved deprecation warnings from here ...
(objc_finish_message_expr): to here. Do not emit deprecation
warnings if the receiver is of type 'id'.
(really_start_method): Install 'deprecation' and 'noreturn'
attributes.
(objc_decl_method_attributes): Carefully filter out the list of
attributes, allowing only "noreturn", "format", "sentinel" and
"deprecated". In the case of "format", adjust the arguments.
Always process the attributes in the same way no matter if
"sentinel" is in the list or not.
