fa9b85d4df Auto merge of #4881 - krishna-veerareddy:issue-4871-use-mem-take, r=flip1995
Use `mem::take` instead of `mem::replace` when applicable

`std::mem::take` can be used to replace a value of type `T` with `T::default()` instead of `std::mem::replace`.

Fixes issue #4871

changelog: Added lint for [`mem_replace_with_default`]

Fix ICE on `unsound_collection_transmute`

Fixes #4968

Check if `Ty`s are normalizable. It might show hidden false negative, I'm not sure.
Also, the regression tests are placed on two dirs, so move them to `/crashes`. I think it will be easier to find the right place.

84a60c3186 Prevent replace_consts lint within match patterns
Currently `replace_consts` lint applies within match patterns but
the suggestion is incorrect as function calls are disallowed in
them. To fix this we prevent the lint from firing within patterns.

f5d0a452ba 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.

676f14baa0
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`.
