Currently `cmp_nan` lint doesn't detect comparisons with NaN's
if the operands are consts variables so to fix this we evaluate
the const variables first before testing for NaN.
Fix clippy build failure
Clippy build fails because the feature `result_map_or` has been stabilized in v1.41.0 but we still have an explicit feature attribute for it.

Fix false positive with cast_sign_loss lint
`cast_sign_loss` lint incorrectly suggests that the result of `checked_abs`, `rem_euclid` and `checked_rem_euclid` cannot be casted to an unsigned integer without loss.
Fixes#4818#4764#4743
changelog: Fix false positives in `cast_sign_loss` lint
Add lint to detect transmutes from float to integer
Add lint that detects transmutation from a float to an integer and suggests usage of `{f32, f64}.to_bits()` instead.
Fixes#3993
changelog: Add lint `transmute_float_to_int`
Add lint for pub fns returning a `Result` without documenting errors
The Rust Book recommends that functions that return a `Result` type have [a doc comment with an `# Errors` section](https://doc.rust-lang.org/book/ch14-02-publishing-to-crates-io.html#commonly-used-sections) describing the kind of errors that can be returned. This change adds a lint to enforce this. The lint is allow by default; it can be enabled with `#![warn(clippy::missing_errors_doc)]`.
Closes#4854.

Fix false positive in `string_add`.
`clippy::string_add` was popping up in macros.
I'm not sure what clippy's general direction is in these matters, but I can change it to be external macros only too.

I need to sleep now, feel free to pick it up.
The output of the `lint_without_lint_pass` test seems to disappear, I'm not sure why.. :/

Fix FP in manual_swap lint with slice-like types
Fixes#4853
changelog: Fix FP in [`manual_swap`] lint with slice-like types and make it auto applicable
Less needless_doctest_main false positives
This checks if a) the `fn main() {}` function is empty or if the doctest contains a `static`. In both cases don't lint. While this fixes#4858 at the cost of some false negatives, but this seems a better solution than disabling the lint outright. In the long run, using `syn` should solve the issue in the right way.
