Rollup merge of #89234 - nbdd0121:discr, r=jackh726
Disallow non-c-like but "fieldless" ADTs from being casted to integer if they use arbitrary enum discriminant
Code like
```rust
#[repr(u8)]
enum Enum {
Foo /* = 0 */,
Bar(),
Baz{}
}
let x = Enum::Bar() as u8;
```
seems to be unintentionally allowed so we couldn't disallow them now ~~, but we could disallow them if arbitrary enum discriminant is used before 1.56 hits stable~~ (stabilization was reverted).
