This isn't the right way to make a call to `objc_autorelease` a tail call, so I'm closing this for now. If we decide to convert calls to `objc_autorelease` and `objc_retain` to calls to `objc_autoreleaseReturnValue` and `objc_retainAutoreleasedReturnValue` for other reasons in the future, I can reopen this.
