## Description
This adds labels to the icons and moves them away from the search box.
These changes are made together, because they work together, but are based on several complaints:
* The [+/-] thing are a Reddit-ism. They don't look like buttons, but look like syntax <https://rust-lang.zulipchat.com/#narrow/stream/266220-t-rustdoc/topic/More.20visual.20difference.20for.20the.20.2B.2F-.20.20Icons>, <https://github.com/rust-lang/rust/issues/59851> (some of these are laundry lists with more suggestions, but they all mention [+/-] looking wrong)
* The settings, help, and summary buttons are also too hard to recognize <https://lwn.net/Articles/987070/>, <https://github.com/rust-lang/rust/issues/90310>, <https://github.com/rust-lang/rust/issues/14475#issuecomment-274241997>, <https://internals.rust-lang.org/t/improve-rustdoc-design/12758> ("Not all functionality is self-explanatory, for example the [+] button in the top right corner, the theme picker or the settings button.")
The toggle-all and toggle-individual buttons both need done at once, since we want them to look like they go together. This changes them from both being [+/-] to both being arrows.
CC <https://github.com/rust-lang/rust/pull/113074#issuecomment-1677469680> and ``@jsha`` regarding the use of triangles for disclosure, which is what everyone wanted, but was pending a good toggle-all button. This PR adds a toggle-all button that should work.
Settings and Help are also migrated, so that the whole group can benefit from being described using actual words.
The breadcrumbs also get redesigned, so that they use less space, by shrinking the parent module path parts. This is done at the same time as the toolbar redesign because it's, effectively, moving space from the toolbar to the breadcrumbs.
This is aimed at avoiding any line wrapping at desktop sizes.
## Prior art
This style of toolbar, with explicit labels on the buttons, used to be more popular. It's not very common in web browsers nowadays, and for truly universal icons like :arrow_left: I can understand why, but words are great when icons fail.

Apply size optimizations to panic machinery and some cold functions
* std dependencies gimli and addr2line are now built with opt-level=s
* various panic-related methods and `#[cold]` methods are now marked `#[optimize(size)]`
Panics should be cold enough that it doesn't make sense to optimize them for speed. The only tradeoff here is if someone does a lot of backtrace captures (without panics) and printing then the opt-level change might impact their perf.
Seems to be the first use of the optimize attribute. Tracking issue #54882

A partial stabilization that only affects:
- AllocType<T>::new_uninit
- AllocType<T>::assume_init
- AllocType<[T]>::new_uninit_slice
- AllocType<[T]>::assume_init
where "AllocType" is Box, Rc, or Arc
|
|
- `new_zeroed` variants move to `new_zeroed_alloc`
- the `write` fn moves to `box_uninit_write`
The remainder will be stabilized in upcoming patches, as
it was decided to only stabilize `uninit*` and `assume_init`.

CloneToUninit impls
As per #126799.
Also implements it for `Wtf8` and both versions of `os_str::Slice`.
Maybe it is worth to slap `#[inline]` on some of those impls.

PinCoerceUnsized trait into core
cc ``@Darksonn`` ``@wedsonaf`` ``@ojeda``
This is a PR to introduce a `PinCoerceUnsized` trait in order to make trait impls generated by the proc-macro `#[derive(SmartPointer)]`, proposed by [RFC](https://github.com/rust-lang/rfcs/blob/e17e19ac7ad1c8ccad55d4babfaee1aa107d1da5/text/3621-derive-smart-pointer.md#pincoerceunsized-1), sound. There you may find explanation, justification and discussion about the alternatives.
Note that we do not seek stabilization of this `PinCoerceUnsized` trait in the near future. The stabilisation of this trait does not block the eventual stabilization process of the `#[derive(SmartPointer)]` macro. Ideally, use of `DerefPure` is more preferrable except this will actually constitute a breaking change. `PinCoerceUnsized` emerges as a solution to the said soundness hole while avoiding the breaking change. More details on the `DerefPure` option have been described in this [section](https://github.com/rust-lang/rfcs/blob/e17e19ac7ad1c8ccad55d4babfaee1aa107d1da5/text/3621-derive-smart-pointer.md#derefpure) of the RFC linked above.
Earlier discussion can be found in this [Zulip stream](https://rust-lang.zulipchat.com/#narrow/stream/136281-t-opsem/topic/Pin.20and.20soundness.20of.20unsizing.20coercions) and [rust-for-linux thread](https://rust-lang.zulipchat.com/#narrow/stream/425075-rust-for-linux/topic/.23.5Bderive.28SmartPointer.29.5D.20and.20pin.20unsoundness.20rfc.233621).

Clean and enable `rustdoc::unescaped_backticks` for `core/alloc/std/test/proc_macro`
I am not sure if the lint is supposed to be "ready enough" (since it is `allow` by default), but it does catch a couple issues in `core` (`alloc`, `std`, `test` and `proc_macro` are already clean), so I propose making it `warn` in all the crates rendered in the website.

They are all clean now, so enable the lint to keep them clean going forward.

The previous commit updated `rustfmt.toml` appropriately. This commit is
the outcome of running `x fmt --all` with the new formatting options.

Clean up more comments near use declarations
#125443 will reformat all use declarations in the repository. There are a few edge cases involving comments on use declarations that require care. This PR fixes them up so #125443 can go ahead with a simple `x fmt --all`. A follow-up to #126717.

There are some comments describing multiple subsequent `use` items. When
the big `use` reformatting happens some of these `use` items will be
reordered, possibly moving them away from the comment. With this
additional level of formatting it's not really feasible to have comments
of this type. This commit removes them in various ways:
- merging separate `use` items when appropriate;
- inserting blank lines between the comment and the first `use` item;
- outright deletion (for comments that are relatively low-value);
- adding a separate "top-level" comment.
We also entirely skip formatting for four library files that contain
nothing but `pub use` re-exports, where reordering would be painful.

Stabilize `hint::assert_unchecked`
Make the following API stable, including const:
```rust
// core::hint, std::hint
pub const unsafe fn assert_unchecked(p: bool);
```
This PR also reworks some of the documentation and adds an example.
Tracking issue: https://github.com/rust-lang/rust/issues/119131
FCP: https://github.com/rust-lang/rust/issues/119131#issuecomment-1906394087. The docs update should resolve the remaining concern.

Stabilize `PanicInfo::message()` and `PanicMessage`
Resolves #66745
This stabilizes the [`PanicInfo::message()`](https://doc.rust-lang.org/nightly/core/panic/struct.PanicInfo.html#method.message) and [`PanicMessage`](https://doc.rust-lang.org/nightly/core/panic/struct.PanicMessage.html).
Demonstration of [custom panic handler](https://github.com/StackOverflowExcept1on/panicker):
```rust
#![no_std]
#![no_main]
extern crate libc;
#[no_mangle]
extern "C" fn main() -> libc::c_int {
panic!("I just panic every time");
}
#[panic_handler]
fn my_panic(panic_info: &core::panic::PanicInfo) -> ! {
use arrayvec::ArrayString;
use core::fmt::Write;
let message = panic_info.message();
let location = panic_info.location().unwrap();
let mut debug_msg = ArrayString::<1024>::new();
let _ = write!(&mut debug_msg, "panicked with '{message}' at '{location}'");
if debug_msg.try_push_str("\0").is_ok() {
unsafe {
libc::puts(debug_msg.as_ptr() as *const _);
}
}
unsafe { libc::exit(libc::EXIT_FAILURE) }
}
```
```
$ cargo +stage1 run --release

This is possible now that inline const blocks are stable; the idea was
even mentioned as an alternative when `uninit_array()` was added:
<https://github.com/rust-lang/rust/pull/65580#issuecomment-544200681>
> if it’s stabilized soon enough maybe it’s not worth having a
> standard library method that will be replaceable with
> `let buffer = [MaybeUninit::<T>::uninit(); $N];`
Const array repetition and inline const blocks are now stable (in the
next release), so that circumstance has come to pass, and we no longer
have reason to want `uninit_array()` other than convenience. Therefore,
let’s evaluate the inconvenience by not using `uninit_array()` in
the standard library, before potentially deleting it entirely.

Make both `hint_assert_unchecked` and `const_hint_assert_unchecked`
stable as `hint_assert_unchecked`.
