ahatanak added a comment. Do we still issue a warning even when the struct can be returned in a register? For example, x86 can return a small struct (for example, a struct with one int field) in a single register, in which case it's fine to pass it to performSelector via @selector.
If we should warn only when the method has to return via sret, then it looks like we have to delay issuing the warning until we know where the return value goes (IRGen?).
