Add more infomation about LintStore registration
Backstory: I somehow missed the fact that I needed to register a lint pass in order for it to run, and I spent some time confused until I figured it out. So I wanted to make it clear that a missing `register_(early|late)_pass` call is a likely cause of a lint not running.
changelog: none
Identical arguments on assert macro family
Lint when identical args are used on `assert_eq!`, `debug_assert_eq!`, `assert_ne!` and `debug_assert_ne!` macros.
Added to the lint `eq_op`.
Common functions added to `utils/higher.rs`
Fixes: #3574Fixes: #4694
changelog: Lint on identical args when calling `assert_eq!`, `debug_assert_eq!`, `assert_ne!` and `debug_assert_ne!` macros
Suggest a compatible shell for setup-toolchain.sh
setup-toolchain.sh uses "[[" which is a bash builtin, but the guide
suggests running it with sh. On Ubuntu, /bin/sh points to dash and
running the script fails.

BTreeMap: refactor Entry out of map.rs into its own file
btree/map.rs is approaching the 3000 line mark, splitting out the entry
code buys about 500 lines of headroom.
I've created this PR because the changes I've made in #77438 will push `map.rs` over the 3000 line limit and cause tidy to complain.
I picked `Entry` to factor out because it feels less tightly coupled to the rest of `BTreeMap` than the various iterator implementations.

Sync from rust
Fix rustc breakage by running:
```rust
git subtree push -P src/tools/clippy git@github.com:josephlr/rust-clippy sync-from-rust
```
and then adding a commit that runs `cargo dev fmt`

The wrapper type led to tons of target.target
across the compiler. Its ptr_width field isn't
required any more, as target_pointer_width
is already present in parsed form.
README: sort en/disabling section, fix typos, add note
it took me a while to figure out why `cargo clippy -- -Aclippy::pedantic -Wclippy::items-after-statements` still showed me *all* the lints. At first I thought it was due to the missing spaces in the current example and I debugged that until I stumbled across an issue noting that you have to touch a random file or run `cargo clean` when you're running clippy repeatedly on an unchanged codebase. This PR is an attempt to save the next person some time and also structure the "Allowing/denying lints" section a bit more while we're at it.
