not set ivar_context, uprivate_record or objc_instance_type.
(objc_comptypes, gen_type_name_0): For types 'id' and 'Class',
retrieve protocol list from the pointee rather than the pointer itself;
check TYPE_HAS_OBJC_INFO(...) precondition before accessing
TYPE_OBJC_PROTOCOL_LIST.
(objc_get_protocol_qualified_type): For types 'id' and 'Class',
construct a variant of the pointee as well as the pointer, and
store protocol information in the former. When creating variants
of RECORD_TYPEs, clone their TYPE_LANG_SPECIFIC fields and propagate
TYPE_OBJC_INTERFACE information.
(objc_declare_class): If a TYPE_DECL is looked up, retrieve the
underlying RECORD_TYPE to check for presence of TYPE_OBJC_INTERFACE;
for newly-created RECORD_TYPEs, create a tentative TYPE_OBJC_INTERFACE
holding an IDENTIFIER_NODE.
(objc_finish_message_expr): Check TYPE_HAS_OBJC_INFO(...) before
accessing TYPE_OBJC_PROTOCOL_LIST; Use TYPE_OBJC_INTERFACE instead
of calling lookup_interface(); allow for TYPE_OBJC_INTERFACE holding
an IDENTIFIER_NODE (meaning a @class forward-declaration only).

lookup_interface().
