When added in 7669f04fb0ddc3d71a1fb44dc1c5c00a6564ae99 / #16066, the page
itself was set to scroll. Now it's set so that the `example-wrap` is
scrolling inside the page, so the overflow setting for the content is
irrelevant.

Undo parts of d1291dc8b4
Monomorphise `#[repr(transparent)]` parameterized ADTs before turning
them into an Itanium mangled String.
`#[repr(transparent)]` ADTs currently use the single field to represent
them in their CFI type ID to ensure that they are compatible. However,
if that type involves a type parameter instantiated at the ADT level, as
in `ManuallyDrop`, this will currently ICE as the `Parameter` type
cannot be mangled. Since this happens at lowering time, it should always
be concrete after substitution.

docs/test: add docs and a UI test for `E0514` and `E0519`
No UI test on `E0514`, it would need to compile with a different `rustc` version.

rustdoc: simplify settings, help, and copy button CSS by not reusing
Since there remains only one common CSS rule shared between them, there's no point to it: the block and selector costs more than the single `width` rule saves.
Provide a better error and a suggestion for `Fn` traits with lifetime params
Given `Fn`-family traits with lifetime params in trait bounds like `fn f(_: impl Fn<'a>(&'a str) -> bool)`, we currently produce many unhelpful errors.
This PR allows these situations to suggest simply using Higher-Rank Trait Bounds like `for<'a> Fn(&'a str) -> bool`.
Fixes https://github.com/rust-lang/rust/issues/103490.
Bump rust-installer
`--without=component-a,component-b` now requires full component names. This fixesrust-lang/rust#105755 (rust-lang/rust-installer#119).
dev-static build succeeded, and installer script seems to work (see comment in thread).
Powershell: Use `WaitForExit` instead of `-Wait`
Using the method `WaitForExit` instead of the parameter `-Wait` results in a notable speed up of the `x.ps1` script (~350ms, fairly consistently).
Results:
```
milliseconds before: 1127.7576
milliseconds after: 779.0467
```
I think there are opportunities for further speed up by calling `Get-Command` only once with the pattern `py*` then filtering the returned list.
But I'll leave that for another time (or someone else).

Make trait/impl `where` clause mismatch on region error a bit more actionable
Improve `where` clause suggestions for GATs/methods that have incompatible region predicates in their `where` clauses.
Also addresses this diagnostic that went away https://github.com/rust-lang/rust/pull/106129#discussion_r1056875772
Improve heuristics whether `format_args` string is a source literal
Previously, it only checked whether there was _a_ literal at the span of the first argument, not whether the literal actually matched up. This caused issues when a proc macro was generating a different literal with the same span.
This requires an annoying special case for literals ending in `\n` because otherwise `println` wouldn't give detailed diagnostics anymore which would be bad.
Fixes#106191
Currently, given `Fn`-family traits with lifetime params like
`Fn<'a>(&'a str) -> bool`, many unhelpful errors show up. These are a
bit confusing.
This commit allows these situations to suggest simply using
higher-ranked trait bounds like `for<'a> Fn(&'a str) -> bool`.
kmc-solid: Fix memory ordering in thread operations
Fixes two memory ordering issues in the thread state machine (`ThreadInner::lifecycle`) of the [`*-kmc-solid_*`](https://doc.rust-lang.org/nightly/rustc/platform-support/kmc-solid.html) Tier 3 targets.
1. When detaching a thread that is still running (i.e., the owner updates `lifecycle` first, and the child updates it next), the first update did not synchronize-with the second update, resulting in a data race between the first update and the deallocation of `ThreadInner` by the child thread.
2. When joining on a thread, the joiner has to pass its own task ID to the joinee in order to be woken up later, but in doing so, it did not synchronize-with the read operation, creating possible sequences of execution where the joinee wakes up an incorrect or non-existent task.
Both issue are theoretical and most likely have never manifested in practice because of the stronger guarantees provided by the Arm memory model (particularly due to its barrier-based definition). Compiler optimizations could have subverted this, but the inspection of compiled code did not reveal such optimizations taking place.
