[`unnecessary_literal_unwrap`]: also lint `unwrap_(err_)unchecked`

Use depinfo to discover UI test dependencies
changelog: none
context: https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Building.20test.20dependencies
This restores [the old `EXTERN_FLAGS` method](4cf5bdc60c/tests/compile-test.rs (L67-L75)) of passing `--extern` flags for building UI tests with minor changes
- Unused deps were removed
- It's now a `Vec` of args instead of a command string
- It uses a `BTreeMap` so the extern flags are in alphabetical order and deterministic
I don't know if the `HOST_LIBS` part is still required, but I figured it best to leave it in for now. If the change is accepted we can take a look if it's needed in `rust-lang/rust` after the next sync
This isn't as pleasant as having a `Cargo.toml`, though there is something satisfying about knowing the dependencies are already built and not needing to invoke `cargo`

This commit fixes#11025 by removing checks for `todo!`,
`unimplemented!` and `unreachable!`.

Uplift `clippy::fn_null_check` lint
This PR aims at uplifting the `clippy::fn_null_check` lint into rustc.
## `incorrect_fn_null_checks`
(warn-by-default)
The `incorrect_fn_null_checks` lint checks for expression that checks if a function pointer is null.
### Example
```rust
let fn_ptr: fn() = /* somehow obtained nullable function pointer */
if (fn_ptr as *const ()).is_null() { /* ... */ }
```
### Explanation
Function pointers are assumed to be non-null, checking for their nullity is incorrect.

Mostly followed the instructions for uplifting a clippy lint described here: https://github.com/rust-lang/rust/pull/99696#pullrequestreview-1134072751

[`unnecessary_literal_unwrap`]: don't lint if binding initializer comes from expansion

"try this" -> "try"
Current help messages contain a mix of "try", "try this", and one "try this instead". In the spirit of #10631, this PR adopts the first, as it is the most concise.
It also updates the `lint_message_conventions` test to catch cases of "try this".
(Aside: #10120 unfairly contained multiple changes in one PR. I am trying to break that PR up into smaller pieces.)
changelog: Make help messages more concise ("try this" -> "try").
Add `needless_pass_by_ref_mut` lint
changelog: [`needless_pass_by_ref_mut`]: This PR add a new lint `needless_pass_by_ref_mut` which emits a warning in case a `&mut` function argument isn't used mutably. It doesn't warn on trait and trait impls functions.
Fixes#8863.
New lint [`manual_partial_ord_and_ord_impl`]
Lints when both `PartialOrd` and `Ord` are manually implemented yet the body of `PartialOrd::partial_cmp` isn't `Some(self.cmp(<other>))`.
This is in `correctness` currently but I'm ok with elsewhere.
Closes#10744

Rename `adjustment::PointerCast` and variants using it to `PointerCoercion`
It makes it sounds like the `ExprKind` and `Rvalue` are supposed to represent all pointer related casts, when in reality their just used to share a little enum variants. Make it clear there these are only coercions and that people who see this and think "why are so many pointer related casts not in these variants" aren't insane.
This enum was added in #59987. I'm not sure whether the variant sharing is actually worth it, but this at least makes it less confusing.

Fix changelog PR listings, create them automatically in `fetch_prs_between.sh`
changelog: none
`fetch_prs_between.sh` now finds the date of the newest and oldest merges from GitHub to use in the range, this does add a dependency on https://github.com/cli/cli
It also no longer prints rollups/merges that come from rustc, so only clippy changes should be printed

Pass correct substs to `implements_trait` in `incorrect_impls`
`Copy<T>` does in fact not exist. The substs on the trait_ref contain the `Self` type of the impl as the first parameter, so passing that to `implements_trait`, which then nicely prepends the `Self` type for us does not end will.
fixes #11121
The assertions requires debug assertions inside rustc, which is probably why it didn't fire here. I tested the change locally in rust-lang/rust and it did not ICE anymore.

It makes it sound like the `ExprKind` and `Rvalue` are supposed to represent all pointer related

Fix regex lints for regex 1.9.0
regex 1.9.0 was [just released](https://blog.burntsushi.net/regex-internals/), which changes where the types are defined. Instead of updating the definitions to the ones in 1.9.0 this PR uses [`def_path_def_ids`](https://doc.rust-lang.org/nightly/nightly-rustc/clippy_utils/fn.def_path_def_ids.html) on the canonical paths so that we don't have to worry about third party crate internals
This means that it still works with older regex versions too, and will for any future layout changes. I tested it with 1.8.4 and 1.9.0
changelog: [`INVALID_REGEX`], [`TRIVIAL_REGEX`]: now works with regex 1.9.0
