bors 788c98df59 Auto merge of #111818 - Urgau:uplift_cmp_nan, r=cjgillot 
Uplift `clippy::cmp_nan` lint

This PR aims at uplifting the `clippy::cmp_nan` lint into rustc.

## `invalid_nan_comparisons`

~~(deny-by-default)~~ (warn-by-default)

The `invalid_nan_comparisons` lint checks comparison with `f32::NAN` or `f64::NAN` as one of the operand.

### Example

```rust,compile_fail
let a = 2.3f32;
if a == f32::NAN {}
```

### Explanation

NaN does not compare meaningfully to anything – not even itself – so those comparisons are always false.

-----

Mostly followed the instructions for uplifting a clippy lint described here: https://github.com/rust-lang/rust/pull/99696#pullrequestreview-1134072751
