resolve: Use same rules for disambiguating fresh bindings in `match` and `let`
Resolve `Unit` as a unit struct pattern in
```rust
struct Unit;
let Unit = x;
```
consistently with
```rust
match x {
Unit => {}
}
```
It was previously an error.
(The change also applies to unit variants and constants.)
