Yes, but the compiler knows that by emitting different code when super
is the target, so [self foo] and [super foo] compile down to calls to
objc_msgSend() and objc_msgSendSuper(), respectively.
CBCallNativeMethod() needs to know whether it's been called via SUPER
for the same reason, to decide which dispatch method to call.
