5b0223e8c6 Reword rustc_on_unimplemented errors for Iterator 
- Detect one element array of `Range` type, which is potentially a typo:
   `for _ in [0..10] {}` where iterating between `0` and `10` was intended.
   (#23141)
 - Suggest `.bytes()` and `.chars()` for `String`.
 - Suggest borrowing or `.iter()` on arrays (#36391)
 - Suggest using range literal when iterating on integers (#34353)
 - Do not suggest `.iter()` by default (#50773, #46806)

0e07c4281c Auto merge of #54762 - RalfJung:miri-validate, r=oli-obk 
Prepare miri engine for enforcing validity invariant during execution

In particular, make recursive checking of references optional, and add a `const_mode` parameter that says whether `usize` is allowed to contain a pointer. Also refactor validation a bit to be type-driven at the "leafs" (primitive types), and separately validate scalar layout to catch `NonNull` violations (which it did not properly validate before).

Fixes https://github.com/rust-lang/rust/issues/53826
Also fixes https://github.com/rust-lang/rust/issues/54751

f65d3b5491 switch validation of scalars to be type-driven 
This does not actually regress anything.  It would regress NonNull, but we
didn't handle that correctly previously either.

efd7a31150 in which rightward drift is opposed 
Thanks to reviewers Tyler Mandry (for pointing out that this is
ridiculous and we need a helper function), Niko Matsakis (for pointing
out that the span-calculation code only has a couple free variables),
and Esteban Küber (for pointing out `get_generics`).

aefe9b099a Auto merge of #54609 - kzys:404-search, r=GuillaumeGomez 
Add the library search box on the 404 page

It actually has a link to search already, but it would be better to
have the search "box" as like index.md to be consistent.

<style> can be shared with index.md, but these pages currently
use https://doc.rust-lang.org/rust.css directly.

Fixes #14572.
