Mini changelog update for Rust 1.61.0
I'll do the full release and sync tomorrow, as I sadly don't have the time today. This is a quick update to ensure that Rust's changelog will link to the correct section in our changelog. The change is according to [our docs](8751e47bae/book/src/development/infrastructure/release.md (update-changelogmd))

[dbg_macro] tolerates use of `dbg!` in items which have `#[cfg(test)]` attribute
fix: #8758
changelog: [dbg_macro] tolerates use of `dbg!` in items with `#[cfg(test)]` attribute
Improve "unknown field" error messages
Fixes#8806
Sample output:
```
error: error reading Clippy's configuration file `/home/smoelius/github/smoelius/rust-clippy/clippy.toml`: unknown field `foobar`, expected one of

You can test this by (say) adding `foobar = 42` to Clippy's root `clippy.toml` file, and running `cargo run --bin cargo-clippy`.
Note that, to get the terminal width, this PR adds `termize` as a dependency to `cargo-clippy`. However, `termize` is also [how `rustc_errors` gets the terminal width](481db40311/compiler/rustc_errors/src/emitter.rs (L1607)). So, hopefully, this is not a dealbreaker.

changelog: Enhancements: the "unknown field" error messages for config files now wraps the field names.
Change `Successors` to `impl Iterator<Item = BasicBlock>`
This PR fixes the FIXME in `compiler\rustc_middle\src\mir\mod.rs`.
This can omit several `&`, `*` or `cloned` operations on Successros' generated elements
Add a query for checking whether a function is an intrinsic.
work towards #93145
This will reduce churn when we add more ways to declare intrinsics

add suggestions to rc_clone_in_vec_init
A followup to https://github.com/rust-lang/rust-clippy/pull/8769
I also switch the order of the 2 suggestions, since the loop initialization one is probably the common case.
`@xFrednet` I'm not letting you guys rest for a minute 😅
changelog: add suggestions to [`rc_clone_in_vec_init`]
Fix ICE in `let_unit_value` when calling a static or const callable type
fixes#8821

`undocumented_unsafe_blocks` does not trigger on unsafe trait impls
Closes#8505
changelog: This lint checks unsafe impls NOT from macro expansions and checks ones in macro declarations.
~~`unsafe impl`s from macro invocations don't trigger the lint for now.~~
~~This lint checks unsafe impls from/not from macro expansions~~
Don't lint `vec_init_then_push` when further extended
fixes#7071
This will still lint when a larger number of pushes are done (four currently). The exact number could be debated, but this is more readable then a sequence of pushes so it shouldn't be too large.
changelog: Don't lint `vec_init_then_push` when further extended.
changelog: Remove `mut` binding from `vec_init_then_push` when possible.
Rename `eval_order_dependence` to `mixed_read_write_expression`, move to nursery
As per the [reference](https://doc.rust-lang.org/1.51.0/reference/expressions.html#evaluation-order-of-operands) evaluation order is now defined.
I'm pretty sure rust always compiled with this evaluation order anyways so there's no reason the put an msrv limit on the lint.
changelog: Rename `eval_order_dependence` to `mixed_read_write_expression`, move to nursery
Add `duplicate_mod` lint
Inspired by #8827, warns if there's a single file that is loaded by more than one `mod` item
```rust,ignore
// lib.rs
mod a;
mod b;
```
```rust,ignore
// a.rs
#[path = "./b.rs"]
mod b;
```
It adds a `canonicalize` call per `mod file;` encountered, which I don't think should be too heavy
Integration tests with common modules, e.g. [`test_utils`](2038084cf2/tests/test_utils) doesn't trigger it as each test is compiled separately, however I couldn't figure out a good way to add a test for that
changelog: Add [`duplicate_mod`] lint
Add EarlyBinder
Chalk has no concept of `Param` (e0ade19d13/chalk-ir/src/lib.rs (L579)) or `ReEarlyBound` (e0ade19d13/chalk-ir/src/lib.rs (L1308)). Everything is just "bound" - the equivalent of rustc's late-bound. It's not completely clear yet whether to move everything to the same time of binder in rustc or add `Param` and `ReEarlyBound` in Chalk.
Either way, tracking when we have or haven't already substituted out these in rustc can be helpful.
As a first step, I'm just adding a `EarlyBinder` newtype that is required to call `subst`. I also add a couple "transparent" `bound_*` wrappers around a couple query that are often immediately substituted.

Fix redundant_allocation warning for Rc<Box<str>>
changelog: [`redundant_allocation`] Fixes#8604
Fixes false positives where a fat pointer with `str` type was made thin by another allocation, but that thinning allocation was marked as redundant
Tweak some words improved representation
Hello! Thank you for this awesome project!
This PR has implemented improved representation.
- Use "lib" instead of "lifb"
- Use "triggered" instead of "triggere"
- Use "blacklisted_name" instead of "blackisted_name"
- Use "stabilization" instead of "stabilisation"
- Use "behavior" instead of "behaviour"
- Use "target" instead of "tartet"
- Use "checked_add" instead of "chcked_add"
- Use "anti-pattern" instead of "antipattern"
- Use "suggestion" instead of "suggesttion"
- Use "example" instead of "exampel"
- Use "Cheat Sheet" instead of "Cheatsheet"

Some lintcheck cleanup
A grab bag of smaller changes:
Panics if a crate source isn't valid, and fixes the `ryu` crate entry so it's picked up. Took me a while to realise why I couldn't do `cargo lintcheck --only ryu` 😅
Parses messages with `cargo_metadata`, this catches a few more lints that were ignored because the message had an [expansion field](https://docs.rs/cargo_metadata/latest/cargo_metadata/diagnostic/struct.DiagnosticSpanMacroExpansion.html) that contained a path pointing into `.../.toolchains/...`. It also no longer emits some log lines with `null` as the column
It also merges the `run_clippy_lint` invocations and splits `LintcheckConfig` out into its own file

don't encode only locally used attrs
Part of https://github.com/rust-lang/compiler-team/issues/505.
We now filter builtin attributes before encoding them in the crate metadata in case they should only be used in the local crate. To prevent accidental misuse `get_attrs` now requires the caller to state which attribute they are interested in. For places where that isn't trivially possible, I've added a method `fn get_attrs_unchecked` which I intend to remove in a followup PR.
After this pull request landed, we can then slowly move all attributes to only be used in the local crate while being certain that we don't accidentally try to access them from extern crates.
