Some hir cleanups
It seemed odd to not put `AnonConst` in the arena, compared with the other types that we did put into an arena. This way we can also give it a `Span` without growing a lot of other HIR data structures because of the extra field.

Remove direct dependencies on lazy_static, once_cell and byteorder
The relevant functionality of all three crates is now available and stable in the standard library, i.e. `std::sync::OnceLock` and `{integer}::to_le_bytes`. I think waiting for `LazyLock` (#109736) would give marginally more concise code, but not by much.

rustdoc-search: fix description on aliases in results
This needs to start downloading the descriptions after aliases have been added to the result set.
|
|
Always display stability version even if it's the same as the containing item
Fixes https://github.com/rust-lang/rust/issues/118439.
Currently, if the containing item's version is the same as the item's version (like a method), we don't display it on the item.
This was something done on purpose as you can see [here](https://github.com/rust-lang/rust/blob/e9b7bf011478aa8c19ac49afc99853a66ba04319/src/librustdoc/html/render/mod.rs#L949-L955). It was implemented in https://github.com/rust-lang/rust/pull/30686.
I think we should change this because on pages with a lot of items, if someone arrives (through the search or a link) to an item far below the page, they won't know the stability version unless they scroll to the top, which isn't great.
You can see the result [here](https://rustdoc.crud.net/imperio/display-stability-version/std/pin/struct.Pin.html#method.new).

Properly handle emojis as literal prefix in macros
Do not accept the following
```rust
macro_rules! lexes {($($_:tt)*) => {}}
lexes!(🐛"foo");
```
Before, invalid emoji identifiers were gated during parsing instead of lexing in all cases, but this didn't account for macro pre-expansion of literal prefixes.
Fix #123696.

rustdoc-search: single result for items with multiple paths
Part of #15723
Preview: https://notriddle.com/rustdoc-html-demo-9/reexport-dup/std/index.html?search=hashmap
This change uses the same "exact" paths as trait implementors and type alias inlining to track items with multiple reachable paths. This way, if you search for `vec`, you get only the `std` exports of it, and not the one from `alloc`.
It still includes all the items in the search index so that you can search for them by all available paths. For example, try `core::option` and `std::option`, and notice that the results page doesn't show duplicates, but still shows all the items in their respective crates.

Fix copy path button
Currently, on all nightly docs, clicking on the "copy path" button triggers a JS error. It's because changes in https://github.com/rust-lang/rust/pull/123706 forgot to update the JS (it contained an image before but not anymore).
I had to make some small changes in the CSS to fix the display when the button was clicked as well.

Stabilize checking of cfgs at compile-time: `--check-cfg` option
This PR stabilize the `--check-cfg` CLI option of `rustc` (and `rustdoc`) :tada:.
In particular this PR does two things:
1. it makes the `--check-cfg` option stable
2. and it moves the documentation to the stable books

rustdoc: update the module-level docs of `rustdoc::clean`
Let's update this 11-year-old documentation.
This would've helped me greatly when first starting out.
Please point out if I should add, clarify or correct anything.
I plan on looking through the rustc dev guide later to see if anything can be expanded upon over there, too.

In some cases `DUMMY_SP` is already imported. In other cases this commit
adds the necessary import, in files where `DUMMY_SP` is used more than
once.

Correctly handle inlining of doc hidden foreign items
Fixes #123435.
In case a foreign item has doc(hidden) attribute, we simply merged its attributes with the re-export's, making it being removed once in the `strip_hidden` pass.
The solution was to use the same as for local reexported items: merge attributes, but not some of them (like `doc(hidden)`).
I originally checked if we could simply update `Item::is_doc_hidden` method to use `self.inline_stmt_id.is_some_and(|def_id| tcx.is_doc_hidden(def_id))` but unfortunately, it added (local) items that shouldn't be inlined. At least it unifies local and foreign items inlining, which I think is the best course of action here.

According to <https://caniuse.com/?search=svg%20favicon>,
SVG favicons are supported in everything but Safari.
When I actually try it in Safari, it's downloading all
three favicons, and nothing looks different when I disable
the 16x16 one.
<https://dev.to/masakudamatsu/favicon-nightmare-how-to-maintain-sanity-3al7>,
which is linked from caniuse above, recommends an ico.
However, the reason they recommend it is the apps that
only support /favicon.ico exactly, and rustdoc can't assume
it will be installed to the site root, so it's unfortunately
up to the webmaster to make sure it's set up.

fmease:rustdoc-synth-auto-yeet-item-param-env-clauses, r=GuillaumeGomez
rustdoc: synthetic auto: filter out clauses from the implementor's ParamEnv
... not just the elaborated clauses.
Fixes another regression introduced by me in #123340, oops!
Fixes https://github.com/rust-lang/rust/pull/123340#issuecomment-2034195786, cc ``@tamird.``
An earlier local iteration of branch `rustdoc-simplify-auto-trait-impl-synth` (PR #123340) contained a fix for issue #111101 before I decided to limit the scope. I must've introduced this bug when manually reverting that part of the code.

rustdoc: slightly clean up the synthesis of blanket impls
Small follow-up to #123340 as promised in https://github.com/rust-lang/rust/pull/123340#discussion_r1546918604. No functional changes whatsoever.
* inline the over-engineered “type namespace” (struct) `BlanketImplFinder` just like I did with `AutoTraitFinder` in #123340
* use the new `synthesize_*` terminology over the old nondescript / misleading `get_*` one
* inline a `use super::*;` (not super modular, lead to `clean/mod.rs` (!) accumulating cruft)
* use `tracing` properly
