more than just `&self` in non-standard implementations.

non-standard method signature
Fixes#9520
`invalid_regex`: Show full error when string value doesn't match source
changelog: [`invalid_regex`]: Show full error when parsing non-literals or regular strings containing escape sequences
Fixes#4170, the escape sequence there causes the span to be incorrect which will have caused most of the confusion
Move format_args!() into AST (and expand it during AST lowering)
Implements https://github.com/rust-lang/compiler-team/issues/541
This moves FormatArgs from rustc_builtin_macros to rustc_ast_lowering. For now, the end result is the same. But this allows for future changes to do smarter things with format_args!(). It also allows Clippy to directly access the ast::FormatArgs, making things a lot easier.
This change turns the format args types into lang items. The builtin macro used to refer to them by their path. After this change, the path is no longer relevant, making it easier to make changes in `core`.
This updates clippy to use the new language items, but this doesn't yet make clippy use the ast::FormatArgs structure that's now available. That should be done after this is merged.

Add machine applicable suggestion for `bool_assert_comparison`
Fixes#7598
Also closes#8118, it had already been fixed by an earlier change but I've added a test for it
changelog: [`bool_assert_comparison`] The suggestion is now machine applicable
Use UnordMap and UnordSet for id collections (DefIdMap, LocalDefIdMap, etc)
This PR changes the `rustc_data_structures::define_id_collections!` macro to use `UnordMap` and `UnordSet` instead of `FxHashMap` and `FxHashSet`. This should account for a large portion of hash-maps being used in places where they can cause trouble.
The changes required are moderate but non-zero:
- In some places the collections are extracted into sorted vecs.
- There are a few instances where for-loops have been changed to extends.
~~Let's see what the performance impact is. With a bit more refactoring, we might be able to get rid of some of the additional sorting -- but the change set is already big enough. Unless there's a performance impact, I'd like to do further changes in subsequent PRs.~~
Performance does not seem to be negatively affected ([perf-run here](https://github.com/rust-lang/rust/pull/106977#issuecomment-1396776699)).

Fix spelling inconsistence of `mdBook`
I was reading both [mdBook Documentation](https://rust-lang.github.io/mdBook/) and [The Clippy Book](https://doc.rust-lang.org/nightly/clippy/development/infrastructure/book.html#the-clippy-book) and felt that it's easier to read to unify the notation of `mdBook`.
