The test does not work on cross-compiled targets because the --target
flag was not passed to rustc inside the test. This commit fixes that by
adding the flag to the invocations.
Note that the test still fails on cross-compiled targets using
remote-test, as remote-test is not capable (yet) of sending back to the
host system the *.profraw file generated by the instrumentation.
Because of that, this is only a partial fix, and the test has been
ignored on cross-compilation.
PR #98758 introduced code to avoid redundant assertions in derived code
like this:
```
let _: ::core::clone::AssertParamIsClone<u32>;
let _: ::core::clone::AssertParamIsClone<u32>;
```
But the predicate `is_simple_path` introduced as part of this failed to
account for generic arguments. Therefore the deriving code erroneously
considers types like `Option<bool>` and `Option<f32>` to be the same.
This commit fixes `is_simple_path`.
Fixes#103157.
The two rules within it can and should be done without the separate
media query:
* There ain't no rule saying a viewport can't be `700.5px` wide, since
hardware pixels can be finer than CSS pixels.
* The rule for the first example-wrap child should probably apply
on mobile.
* The rule for the source sidebar is overriden by the mobile rule
setting `max-width: 100vw`, so it can be merged with the rest
of the styles.
Remove "execute" bit from lock file permissions
Previously, flock would set the "execute" bit on Rust lock files. That makes no sense.
This patch clears the "execute" bit on Rust lock files.
See issue #102531.
Add `Box<[T; N]>: TryFrom<Vec<T>>`
We have `[T; N]: TryFrom<Vec<T>>` (#76310) and `Box<[T; N]>: TryFrom<Box<[T]>>`, but not this combination.
`vec.into_boxed_slice().try_into()` isn't quite a replacement for this, as that'll reallocate unnecessarily in the error case.
**Insta-stable, so needs an FCP**
(I tried to make this work with `, A`, but that's disallowed because of `#[fundamental]` https://github.com/rust-lang/rust/issues/29635#issuecomment-1247598385)
The final return value doesn't need to be tried at all -- we can just
return the checked option directly. The optimizer can probably figure
this out anyway, but there's no need to make it work here.

Do not register placeholder `RegionOutlives` obligations when `considering_regions` is false
**NOTE:** I'm kinda just putting this up for discussion. I'm not certain this is correct...?
This was introduced in [`608625d`](608625dae9 (diff-6e54b18681342ec725d75591dbf384ad08cd73df29db00485fe51b4e90f76ff7R361)).
Interestingly, we only check `data.has_placeholders()` for `RegionOutlives`, and not for `TypeOutlives`... why? For the record, that different treatment between `RegionOutlives` and `TypeOutlives` is why the fix "The compiling succeeds when all `'a : 'b` are replaced with `&'a () : 'b`" in #100689 _"works"_, but it seems like an implementation detail considering this.
Also, why do we care about placeholder regions being registered if `considering_regions` is false? It doesn't seem to affect any UI tests, for example.

Add `unused_format_specs` lint
Currently catches two cases:
An empty precision specifier:
```rust
// the same as {}
println!("{:.}", x);
```
And using formatting specs on `format_args!()`:
```rust
// prints `x.`, not `x .`
println("{:5}.", format_args!("x"));
```

Sometimes it is convenient to return a subdiagnostic enum where one or
more of the variants don't add anything to the diagnostic.

Documentation comments shouldn't affect the diagnostic derive in any
way, but explicit support has to be added for ignoring the `doc`
attribute.
