We could emit a call to `@llvm.objc.retain` instead of the call to 
`@llvm.objc.retainAutoreleasedReturnValue`, but this doesn't seem to happen 
often and ARC optimizer can remove or replace the call anyway, so I'm just 
letting the front-end emit `@llvm.objc.retainAutoreleasedReturnValue` for 
simplicity.
