Analog to 1c0dc18 rust-lang#92356

Performing UTF-8 decode outside the JSON module makes more sense in almost all cases.

Also adjust CSS so this doesn't produce excess padding/margin.

It previously pointed to rust-lang#57563, the conglomerate issue for
`const fn` (presumably under the feature gate `const_fn`).
`const_fn_trait_bounds` weren't mentioned here, so this commit changes
its tracking issue to a new one.

I missed this in rust-lang#89757; it made
`x.py test src/bootstrap` very slow.

Previously, rustbuild would give strange errors if you tried to reuse the same build directory under two names:

```

$ ../x.py check

    Finished dev [unoptimized] target(s) in 35.27s

```

This fixes the error. Reusing the same build directory is useful if you want to test path-things in
bootstrap itself, without having to recompile it each time.

For good measure, this also reruns the build script when PATH changes.

Suggest 1-tuple parentheses on exprs without existing parens

A follow-on from rust-lang#86116, split out from rust-lang#90677.

This alters the suggestion to add a trailing comma to create a 1-tuple - previously we would only apply this if the relevant expression was parenthesised. We now make the suggestion regardless of parentheses, which reduces the fragility of the check (w.r.t formatting).

e.g.
```rust
let a: Option<(i32,)> = Some(3);
```

gets the below suggestion:

```rust
let a: Option<(i32,)> = Some((3,));
//                           ^ ^^
```

This change also improves the suggestion in other ways, such as by only making the suggestion if the types would match after the suggestion is applied and making the suggestion a multipart suggestion.

Cleanup c_str.rs

Some code cleanups in `c_str.rs`.
No functional changes.

Impl {Add,Sub,Mul,Div,Rem,BitXor,BitOr,BitAnd}Assign<$t> for Wrapping<$t> for rust 1.60.0

Tracking issue rust-lang#93204

This is about adding basic integer operations to the `Wrapping` type:

```rust
let mut value = Wrapping(2u8);
value += 3u8;
value -= 1u8;
value *= 2u8;
value /= 2u8;
value %= 2u8;
value ^= 255u8;
value |= 123u8;
value &= 2u8;
```

Because this adds stable impls on a stable type, it runs into the following issue if an `#[unstable(...)]` attribute is used:

```
an `#[unstable]` annotation here has no effect
note: see issue rust-lang#55436 <rust-lang#55436> for more information
```

This means - if I understood this correctly - the new impls have to be stabilized instantly.
Which in turn means, this PR has to kick of an FCP on the tracking issue as well?

This impl is analog to 1c0dc18 rust-lang#92356 for the `Saturating` type ``@dtolnay``  ``@Mark-Simulacrum``

Don't allow {} to refer to implicit captures in format_args.

Fix linking stage1 toolchain in `./x.py setup`

Closes [92319](rust-lang#92319)

Fix linking stage1 toolchain in `./x.py setup`. I guess this can be considered a follow up to rust-lang#89212 by `````@Sl1mb0.`````

We create 2 directories and 1 file that are required by rustup to [link a custom toolchain from path](https://github.com/rust-lang/rustup/blob/5225e87a5d974ab5f1626bcb2a7b43f76ab883f0/src/toolchain.rs#L479-L497).

Linkify sidebar headings for sibling items

Also adjust CSS so this doesn't produce excess padding/margin.

Note: I tried and failed to write a test with browser-UI-test. First I tried to `assert-property: (".block.mod h3 a", {"href": "index.html#macros"})`. But the `href` that gets read out is the fully-quallified URL, starting with `file:///`. That URL will differ depending on what path the test is run from, so that doesn't work.

Next I tried clicking on the appropriate sidebar link, and verifying that the appropriate heading on the next page is highlighted with the right background color. However, that also didn't work: according to browser-UI-test, the targeted heading was plain white. However, running with no-headless, I could see that it actually was yellow. I suspect this is a bug in the older version of Chromium used with browser-UI-test's bundled puppeteer, since it doesn't reproduce on latest Chrome.

Fixes rust-lang#92957

…s-const_fn_trait_bound, r=oli-obk

Update tracking issue for `const_fn_trait_bound`

It previously pointed to rust-lang#57563, the conglomerate issue for `const fn` (presumably under the feature gate `const_fn`). This tracking issue doesn't mention anything about `const_fn_trait_bound`(the only occurrence of "trait bound" is for the now-removed `?const Trait` syntax), which can be confusing to people who want to find out more about trait bounds on `const fn`s. This pull request changes the tracking issue to one meant specifically for `const_fn_trait_bound`, rust-lang#93706, which can help collect information on this feature's stabilization and point users towards `const_trait_impl` if they're looking for const-in-const-contexts trait bounds.

Fixes rust-lang#93679.

Rerun bootstrap's build script when RUSTC changes
