This commit makes `AdtDef` use `Interned`. Much the commit is tedious
changes to introduce getter functions. The interesting changes are in
`compiler/rustc_middle/src/ty/adt.rs`.
RustWrapper: add missing include
This is required after LLVM change 3c4410dfcaaf (aka
https://reviews.llvm.org/D121168) did some includes cleanup.

Allow `cargo run` instead of `cargo run -p bootstrap`
This was part of `@Mark-Simulacrum` 's original PR in ecb424f129,
but I missed it when writing #92260.
This also has the side effect of allowing `cargo build --bins` instead of `cargo build -p bootstrap --bins`. I'm not sure when you would want to run cargo build/check/test without going through bootstrap, but this still allows you to do so as long as you pass `-p` for all the crates you want to build.
Improve rustdoc book
This pull-request improves the `rustdoc` book by doing some (light) cleanup, by merging some stuff, by adding some missing stuff (like tracking issues links, for those who had one) and also by moving some chapter's into sub-chapter's to improve the flow of the book.
~~Note that I locally tested with `mdbook-lintcheck` that no links became accidentally broken.~~ (Not enough, ;-))

Unify impl blocks by wrapping them into a div
The blanket and "auto traits" sections are wrapped into a `div` with an ID. This PR fixes this incoherence by wrapping each impl section (the "deref impl" and the "inherent impl" sections were missing it). It'll also make some tests simpler to write.

Document new recommended use of `FromIterator::from_iter`
#90107
Most of the added prose was paraphrased from the links provided in the issue. The suggested `VecDeque` example seemed to make the point well enough so I just used that.
Better error for normalization errors from parent crates that use `#![feature(generic_const_exprs)]`
This PR implements a somewhat rudimentary heuristic to suggest using `#![feature(generic_const_exprs)]` in a child crate when a function from a foreign crate (that may have used `#![feature(generic_const_exprs)]`) fails to normalize during codegen.

diagnostics: use rustc_on_unimplemented to recommend `[].iter()`
To make this work, the `#[rustc_on_unimplemented]` data needs to be used to
report method resolution errors, which is most of what this commit does.
Fixes#94581
Constify `Index{,Mut}` for `[T]`, `str`, and `[T; N]`
Several panic functions were rewired (via `const_eval_select`) to simpler implementations that do not require formatting for compile-time usage.

Merge `#[deprecated]` and `#[rustc_deprecated]`
The first commit makes "reason" an alias for "note" in `#[rustc_deprecated]`, while still prohibiting it in `#[deprecated]`.
The second commit changes "suggestion" to not just be a feature of `#[rustc_deprecated]`. This is placed behind the new `deprecated_suggestion` feature. This needs a tracking issue; let me know if this PR will be approved and I can create one.
The third commit is what permits `#[deprecated]` to be used when `#![feature(staged_api)]` is enabled. This isn't yet used in stdlib (only tests), as it would require duplicating all deprecation attributes until a bootstrap occurs. I intend to submit a follow-up PR that replaces all uses and removes the remaining `#[rustc_deprecated]` code after the next bootstrap.

Improve suggestion when casting usize to (possibly) wide pointer
I thought #92125 was a wonderful idea, so I went ahead and took a stab at it. Not sure if my approach is the best going forward, but I'm happy with the improvement in the error message.
Iwill definitely address any changes if people are more opinionated with the wordings or want more features.
Also, do I need to add a new error code?
(Fixes#92125)
Treat constant values as mir::ConstantKind::Val
Another step that is necessary for the introduction of Valtrees: we don't want to treat `ty::Const` instances of kind `ty::ConstKind::Value` as `mir::ConstantKind::Ty` anymore.

add `#[rustc_pass_by_value]` to more types
the only interesting changes here should be to `TransitiveRelation`, but I believe to be highly unlikely that we will ever use a non `Copy` type with this type.
Ignore `close_read_wakes_up` test on SGX platform
PR #94714 enabled the `close_read_wakes_up` test for all platforms. This is incorrect. This test should be ignored at least for the SGX platform.

Warn users about `||` in let chain expressions
Or more specifically, warn that `||` operators are forbidden.
This PR is simple so I guess anyone can review 🤷

Add Iterator::collect_into
This PR adds `Iterator::collect_into` as proposed by ``@cormacrelf`` in #48597 (see https://github.com/rust-lang/rust/pull/48597#issuecomment-842083688).
Followup of #92982.
This adds the following method to the Iterator trait:
```rust
fn collect_into<E: Extend<Self::Item>>(self, collection: &mut E) -> &mut E
```
Mention intent of `From` trait in its docs
This pr is a docs modification to add to the documentation of the `From` trait a note about its intent as a perfect conversion. This is already stated in the `TryFrom` docs so this is simply adding that information in a more visible way.
To make this work, the `#[rustc_on_unimplemented]` data needs to be used to
report method resolution errors, which is most of what this commit does.
Fixes#94581
