We have a migration warning but no lint for users who have enabled the new edition.
This form of check allows performing snapshot tests (à la `src/test/ui`) on rustdoc HTML output, making it easier to create and update tests. See this Zulip thread [1] for more information about the motivation for this change. [1]: https://zulip-archive.rust-lang.org/stream/266220-rustdoc/topic/HTML.20snapshot.20tests.html#262651142

Add unchecked downcast methods
```rust
impl dyn Any (+ Send + Sync) {
pub unsafe fn downcast_ref_unchecked<T: Any>(&self) -> &T;
pub unsafe fn downcast_mut_unchecked<T: Any>(&mut self) -> &mut T;
}
impl<A: Allocator> Box<dyn Any (+ Send + Sync), A> {
pub unsafe fn downcast_unchecked<T: Any>(&self) -> Box<T, A>;
}
```
Implement `@snapshot` check for htmldocck This form of check allows performing snapshot tests (à la `src/test/ui`) on rustdoc HTML output, making it easier to create and update tests.

…st, r=estebank Suggest the `pat_param` specifier before `|` on 2021 edition Ran into this today after writing some Rust for the first time in a while. r? `@estebank`
…tion, r=camelid Remove incorrect newline from float cast suggestion
Use let_else in some more places in rustc_lint Follow-up of rust-lang#91018 and rust-lang#89933 . Also cc rust-lang#90985 which added the first let_else uses to rustc_lint.
…bank Fix ICE when `yield`ing in function returning `impl Trait` Change an assert to a `delay_span_bug` and remove an unwrap, that should fix it. Fixes rust-lang#91477
