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

/// work around this by using a [match guard], such as:

///

/// # let x = 42.0;

///

/// match x {

/// y if y == 5.0 => {}
