[`never_loop`]: Fix FP with let..else statements.
Fixes#9356
This has been bugging me for a while, so I thought I'd take a stab at it! I'm completely uncertain about the quality of my code, but I think it's an alright start, so opening this PR to get some feedback from more experienced clippy people :)
changelog: [`never_loop`]: Fix FP with let..else statements
[`nonstandard_macro_braces`] Do not modify macro arguments
fix#9498
based on top of https://github.com/rust-lang/rust-clippy/pull/9471
Also simplify the lint by not caring about code format which should be `rustfmt` job, and turn the lint into machine Applicable
changelog: Suggestion: [`nonstandard_macro_braces`]: The suggestion is now machine applicable and will no longer replace brackets inside the macro argument.

Changelog for Rust 1.64 🍎
The normal release preparation dance. I've written the changelog like the version has already been released. The PR can be approved and then merged by anyone after the release of Rust 1.64 🙃

Fix ICE in `unnecessary_to_owned`
Fixes#9504
Compiler generated call `into_future` nodes return empty substs which we need when checking it's predicates. Handle this by simply exitting when we encounter one. This change introduces false negatives in place of the ICEs.

[arithmetic-side-effects] Finish non-overflowing ops
Extends https://github.com/rust-lang/rust-clippy/pull/9474 to also take into consideration "raw" binary operations. For example, `let a = b / 2` and `let a = 1 * b` won't trigger the lint.

Add `#[allow(unused)]` to test in `cargo dev new_lint`
`rustfix` tests don't automatically apply `-Aunused` which leads to some tests having `_workarounds`, add it to new test files automatically so people don't have to worry about it

Update rust-analyzer documentation, mention linkedProjects
r-a uses the `rustc-dev` component from the rustup installed toolchain clippy specifies so it doesn't need to be manually installed. Also remove references to nightly r-a as the feature is long stable
I discovered `rust-analyzer.linkedProjects` recently and it has made working on the crates not referenced by the `clippy` crate so much nicer

Make module-style lints resilient to --remap-path-prefix
changelog: [`self_named_module_files`], [`mod_module_files`]: Make module-style lints resilient to `--remap-path-prefix`
Without this if a user has configured `--remap-path-prefix` to be used for a prefix containing the current source directory the lints would silently fail to generate a warning.
`bool_to_int_with_if` inverse case patch
Enhances `bool_to_int_with_if` such that it can also catch an inverse bool int conversion scenario, and makes the right suggestion for converting to int with a prefixed negation operator.
changelog: [`bool_to_int_with_if`]: Now correctly detects the inverse case, `if bool { 0 } else { 1 }`
Migrate write.rs to a late pass
changelog: Migrates write.rs from a pre expansion pass to a late pass
changelog: [`positional_named_format_parameters`] is renamed in favour of the rustc lint `named_arguments_used_positionally`
- Macros are now identified by diagnostic items, so will no longer lint user defined macros named, e.g. a custom `print!`
- `print_literal`/`write_literal` no longer lint no longer lint literals that come from macro expansions, e.g. `env!("FOO")`
- `print_with_newline`/`write_with_newline` no longer lint strings with any internal `\r` or `\n`s
~~A false negative, `print_literal`/`write_literal` don't lint format strings that produce `FormatSpec`s, e.g. ones containing pretty print/width/align specifiers~~
Suggestion changes:
- ~~`print_literal`/`write_literal` no longer have suggestions, as the spans for the `{}`s were not easily obtainable~~
- `print_with_newline`/`write_with_newline` has a better suggestion for a sole literal newline, but no longer has suggestions for len > 1 strings that end in a literal newline
- ~~`use_debug` spans are less precise, now point to the whole format string~~
The diff for write.rs is pretty unwieldy, other than for the `declare_clippy_lint!`s I think you'd be better off viewing it as a brand new file rather than looking at the diff, as it's mostly written from scratch

Fix `unused_peekable` closure and `f(&mut peekable)` false positives
changelog: Fix [`unused_peekable`] false positive when peeked in a closure or called as `f(&mut peekable)`
The `return`/`break` changes aren't part of the fix, they allow an earlier return in some cases. `break` is replaced with `return` for style purposes as they do the same thing in this case

fix `implements_trait` and `in_external_macro` import path

Don't panic on invalid shift while constfolding
Instead of panicking on invalid shifts while folding constants we simply give up. Fixes#9463
Notice the "attempt to shift right by `1316134912_u32`", which seems weird. AFAICS it comes from rustc itself.
