Rollup merge of #116284 - RalfJung:no-nan-match, r=cjgillot

Browse source 
make matching on NaN a hard error, and remove the rest of illegal_floating_point_literal_pattern

These arms would never be hit anyway, so the pattern makes little sense. We have had a future-compat lint against float matches in general for a *long* time, so I hope we can get away with immediately making this a hard error.

This is part of implementing https://github.com/rust-lang/rfcs/pull/3535.

Closes https://github.com/rust-lang/rust/issues/41620 by removing the lint.

https://github.com/rust-lang/reference/pull/1456 updates the reference to match.

/// The `illegal_floating_point_literal_pattern` lint detects
/// floating-point literals used in patterns.
///
/// ### Example
///
/// ```rust
/// let x = 42.0;
///
/// match x {
/// 5.0 => {}
/// _ => {}
/// }
/// ```
///
/// {{produces}}
///
/// ### Explanation
///
/// Previous versions of the compiler accepted floating-point literals in
/// patterns, but it was later determined this was a mistake. The
/// semantics of comparing floating-point values may not be clear in a
/// pattern when contrasted with "structural equality". Typically you can
/// work around this by using a [match guard], such as:
///
/// ```rust
/// # let x = 42.0;
///
/// match x {
/// y if y == 5.0 => {}
/// _ => {}
/// }
/// ```
///
/// This is a [future-incompatible] lint to transition this to a hard
/// error in the future. See [issue #41620] for more details.
///
/// [issue #41620]: https://github.com/rust-lang/rust/issues/41620
