The generated code for function bodies produces an `unreachable_code`
warning if the function has a `!` return type.
The offending bit is:
```rust
if let Some(__ret) == None::<!> {
// unreachable
}
```
This PR fixes the warning by simply adding `#[allow(unreachable_code)]`
to the return statement. It also adds a test for it.
This problem can only be triggered on nightly with the `never_type`
feature enabled, but it is easy to fix here.
