Rollup merge of #145273 - estebank:not-not, r=samueltardieu

Account for new `assert!` desugaring in `!condition` suggestion

`rustc` in rust-lang/rust#122661 is going to change the desugaring of `assert!` to be

```rust
match condition {
    true => {}
    _ => panic!(),
}
```
which will make the edge-case of `condition` being `impl Not<Output = bool>` while not being `bool` itself no longer a straightforward suggestion, but `!!condition` will coerce the expression to be `bool`, so it can be machine applicable.

Transposing rust-lang/rust-clippy#15453 to the rustc repo.
