	* sendmsg.c: Include objc/runtime.h instead of objc/objc-api.h.
	Include objc-private/module-abi-8.h and objc-private/selector.h
	instead of objc/encoding.h.

	super->class.
	(method_get_first_argument, method_get_next_argument): Declare
	locally.
	(class_get_instance_method): Declare before using.
	(objc_msg_sendv): Use 'struct objc_method' instead of 'Method'.
	(__objc_init_dispatch_tables, __objc_send_initialize): Use
	sel_registerName() instead of sel_register_name().
