It makes it clearer that the `Namespace` is the one requested by the
disambiguator, rather than the actual namespace of the item. It said
that in the docs before, but now you can tell in the code so it reduces
the potential for confusion.
rustdoc: Remove unnecessary optional
Previously, the HTML output format was represented by both
`Some(OutputFormat::Html)` and `None` so there's no need to have an
optional. Instead, `OutputFormat::Html` is explicitly the default and we
no longer have a "tri-state enum".
r? `````@GuillaumeGomez`````
* Reuse memory
* simplify `next_def_id`, avoid multiple hashing and unnecessary lookups
* remove `all_fake_def_ids`, use the global map instead (probably not a good step toward parallelization, though...)
* convert `add_deref_target` to iterative implementation
* use `ArrayVec` where we know the max number of elements
* minor touchups here and there
* avoid building temporary vectors that get appended to other vectors
At most places I may or may not be doing the compiler's job is this PR.

Fix rustdoc text selection for page titles
Fixes text selection of page titles by placing the `h1.fqn span.in-band` element before `h1.fqn span.out-of-band`.

Retry of PR #81397 due to merge conflicts confusing me. Recreated the same changes as in that PR, but now when I run `./x.py doc library/std`, no changes I make to `src/librustdoc/html/render/mod.rs` to the file are reflected in the built doc files, even if I delete the `build` folder. I'm guessing there's some cache I'm missing?

Split rustdoc JSON types into separately versioned crate
For now just an in-tree change.
In the future, this may be exposed as a standalone crate with standard semver.
rustdoc: Render HRTB correctly for bare functions
The angle brackets were not rendered, so code like this:
some_func: for<'a> fn(val: &'a i32) -> i32
would be rendered as:
some_func: fn'a(val: &'a i32) -> i32
However, rendering with angle brackets is still invalid syntax:
some_func: fn<'a>(val: &'a i32) -> i32
so now it renders correctly as:
some_func: for<'a> fn(val: &'a i32) -> i32
-----
However, note that this code:
some_trait: dyn for<'a> Trait<'a>
will still render as:
some_trait: dyn Trait<'a>
which is not invalid syntax, but is still unclear. Unfortunately I think
it's hard to fix that case because there isn't enough information in the
`rustdoc::clean::Type` that this code operates on. Perhaps that case can
be fixed in a later PR.

Improve URLs handling
Fixes#81330.
Explanations: before this PR, when emptying the search input, we still had `?search=` in the URL, which wasn't very nice. Now, if the search is empty, we drop the `?search=` part.
Also, I realized while working on this PR that when we clicked on a menu link when we were on the search results, the search parameters would look like: `?search=#the-anchor`, which was super weird. Now, it looks like this: `?search=the-search#the-anchor`.
Also, I didn't use the `Url` very nice API because it's not available in any IE version (sadness...).

Make `-Z time-passes` less noisy
- Add the module name to `pre_AST_expansion_passes` and don't make it a
verbose event (since it normally doesn't take very long, and it's
emitted many times)
- Don't make the following rustdoc events verbose; they're emitted many times.
+ build_extern_trait_impl
+ build_local_trait_impl
+ build_primitive_trait_impl
+ get_auto_trait_impls
+ get_blanket_trait_impls
- Remove the `get_auto_trait_and_blanket_synthetic_impls` rustdoc event; it's wholly
covered by get_{auto,blanket}_trait_impls and not very useful.
I found this while working on https://github.com/rust-lang/rust/pull/81275 but it's independent of those changes.
Refractor a few more types to `rustc_type_ir`
In the continuation of #79169, ~~blocked on that PR~~.
This PR:
- moves `IntVarValue`, `FloatVarValue`, `InferTy` (and friends) and `Variance`
- creates the `IntTy`, `UintTy` and `FloatTy` enums in `rustc_type_ir`, based on their `ast` and `chalk_ir` equilavents, and uses them for types in the rest of the compiler.
~~I will split up that commit to make this easier to review and to have a better commit history.~~
EDIT: done, I split the PR in commits of 200-ish lines each

Fix some bugs reported by eslint
Simply went into `src/librustdoc/html/static/` and ran `eslint *.js` in case you want to reproduce. :)

Fix rendering of stabilization version for trait implementors
Rustdoc compares an item's stabilization version with its parent's to not render it if they are the same. Here, the implementor was compared with itself, resulting in the stabilization version never getting shown.
This probably needs a test.
Fixes#80777.

Fix <unknown> queries and add more timing info to render_html
Closes https://github.com/rust-lang/rust/issues/81251.
## Fix `<unknown>` queries
This happened because `alloc_query_strings` was never called.
## Add more timing info to render_html
This still has some issues I'm not sure how to work out:
- `create_renderer` and `renderer_after_krate` aren't shown by default.
I want something like `verbose_generic_activity_with_arg`, but it doesn't exist.
I'm also not sure how to show activities that aren't on by default - I
tried `-Z self-profile -Z self-profile-args=all`, but it didn't show up.

+ build_local_trait_impl

+ get_blanket_trait_impls
- Remove `get_auto_trait_and_blanket_synthetic_impls`; it's wholly
covered by get_{auto,blanket}_trait_impls and not very useful.
This avoids each tool having to separately find and call
`self_profile_alloc_strings`.
- Don't compute the global context if it hasn't yet been computed
This avoids giving extraneous errors about unresolved names if an error
occurs during parsing.
Remove doctree::StructType
Also removes it from the Union type, as unions can only ever be 'Plain'. Adds a new StructType to JSON, 'union', as the easiest way to encode the type of a union there. This leaves only one item in doctree, `Module`.

Deny rustc::internal lints for rustdoc and clippy
- Fix rustc::internal lints for rustdoc
- Deny internal lints only for rustdoc and clippy (previously the lints were ignored for clippy because -Zunstable-options didn't get passed)
