Update iterator_step_by_zero

`std::{f32,f64}::is_nan` isn't a const fn so prevent `cmp_nan`

Detect comparisons with NAN constants
...
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.

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 describing the kind of errors
that can be returned
(https://doc.rust-lang.org/book/ch14-02-publishing-to-crates-io.html#commonly-used-sections ).
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 .

Add custom ICE message that points to Clippy repo
...
This utilizes https://github.com/rust-lang/rust/pull/60584 by setting
our own `panic_hook` and pointing to our own issue tracker instead of
the rustc issue tracker.
This also adds a new internal lint to test the ICE message.
**Potential downsides**
* This essentially copies rustc's `report_ice` function as
`report_clippy_ice`. I think that's how it's meant to be implemented, but
maybe @jonas-schievink could have a look as well =)
The downside of more-or-less copying this function is that we have to
maintain it as well now.
The original function can be found [here][original].
* `driver` now depends directly on `rustc` and `rustc_errors`
Closes #2734

[comparison_chain] #4827 Check `core::cmp::Ord` is implemented
Only emit `comparison_chain` lint, if `cmp` is actually available on the type being compared. Don't emit lint in cases where only `PartialOrd` is implemented.
I haven't yet fully understood [Adjustments](https://doc.rust-lang.org/nightly/nightly-rustc/rustc/ty/adjustment/struct.Adjustment.html ). I would appreciate, if someone could double check whether my usage of [expr_ty](https://doc.rust-lang.org/nightly/nightly-rustc/rustc/ty/struct.TypeckTables.html#method.expr_ty ) in `clippy_lints/src/comparison_chain.rs:91` is correct or if there are cases where using [expr_ty_adjusted](https://doc.rust-lang.org/nightly/nightly-rustc/rustc/ty/struct.TypeckTables.html#method.expr_ty_adjusted ) would lead to a different result when used with `utils::implements_trait`.
