- Refine the "NaN as a special value" top level explanation of f32
- Refine `const NAN` docstring.
- Refine `fn is_sign_positive` and `fn is_sign_negative` docstrings.
- Refine `fn min` and `fn max` docstrings.
- Refine `fn trunc` docstrings.
- Refine `fn powi` docstrings.
- Refine `fn copysign` docstrings.
- Reword `NaN` and `NAN` as plain "NaN", unless they refer to the specific `const NAN`.
- Reword "a number" to `self` in function docstrings to clarify.
- Remove "Returns NAN if the number is NAN" as this is told to be the default behavior in the top explanation.
- Remove "propagating NaNs", as full propagation (preservation of payloads) is not guaranteed.

This updates the standard library's documentation to use the new syntax. The
documentation is worthwhile to update as it should be more idiomatic
(particularly for features like this, which are nice for users to get acquainted
with). The general codebase is likely more hassle than benefit to update: it'll
hurt git blame, and generally updates can be done by folks updating the code if
(and when) that makes things more readable with the new format.
A few places in the compiler and library code are updated (mostly just due to
already having been done when this commit was first authored).

- Make clear that the `Pointer` trait is related to formatting
- Make clear that `&T` (shared reference) implements `Send` (if `T: Send + Sync`)
|
|
This works by doing two things:
- Adding links that are specific to the crate. Since not all primitive
items are defined in `core` (due to lang_items), these need to use
relative links and not intra-doc links.
- Duplicating `primitive_docs` in both core and std. This allows not needing CARGO_PKG_NAME to build the standard library. It also adds a tidy check to make sure they stay the same.

More symbolic doc aliases
A bunch of small changes, mostly adding `#[doc(alias = "…")]` entries for symbolic `"…"`.
Also a small change in documentation of `const` keywords.

Add links in docs for some primitive types
This pull request adds additional links in existing documentation of some of the primitive types.
Where items are linked only once, I have used the `[link](destination)` format. For items in `std`, I have linked directly to the HTML, since although the primitives are in `core`, they are not displayed on `core` documentation. I was unsure of what length I should keep lines of documentation to, so I tried to keep them within reason.
Additionally, I have avoided excessively linking to keywords like `self` when they are not relevant to the documentation. I can add these links if it would be an improvement.
I hope this can improve Rust. Please let me know if there's anything I did wrong!

Update `ptr` docs with regards to `ptr::addr_of!`
This updates the documentation since `ptr::addr_of!` and `ptr::addr_of_mut!` are now stable. One might remove the distinction between the sections `# On packed structs` and `# Examples`, as the old section on packed structs was primarily to prevent users of doing undefined behavior, which is not necessary anymore.
Technically there is now wrong/outdated documentation on stable, but I don't think this is worth a point release 😉
Fixes #83509.

There is also a new section in "how to obtain a pointer", which referen-
ces the `ptr::addr_of!` macros.

On bootstrap the IntoIterator trait is not implemented
yet for arrays.

Cautiously add IntoIterator for arrays by value
Add the attribute described in #84133, `#[rustc_skip_array_during_method_dispatch]`, which effectively hides a trait from method dispatch when the receiver type is an array.
Then cherry-pick `IntoIterator for [T; N]` from #65819 and gate it with that attribute. Arrays can now be used as `IntoIterator` normally, but `array.into_iter()` has edition-dependent behavior, returning `slice::Iter` for 2015 and 2018 editions, or `array::IntoIter` for 2021 and later.

Also remove plus sign in `-0.0 == +0.0` to make it a valid expression.

"semantic equivalence" is too strong a phrasing here, which is why
actually explaining what kind of circumstances might produce a -0
was chosen instead.

Update `bool` and `!` docs

Now that #76934 has merged, we can remove a lot of these! E.g, this is
no longer necessary:
[`Vec<T>`]: Vec

Add array search aliases
Missed this in https://github.com/rust-lang/rust/pull/80068. This one will really fix https://github.com/rust-lang/rust/issues/46075.
The last alias especially I'm a little unsure about - maybe fuzzy search should be fixed in rustdoc instead? Happy to make that change although I'd have to figure out how.
r? ``@m-ou-se`` although cc ``@GuillaumeGomez`` for the search issue.

Add `&mut` as an alias for 'reference' primitive
