* 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?

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...).

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.

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`.

Improve search result tab handling
Fixes#80378.
If the current search result tab is empty, it picks the first non-empty one. If all are empty, the current one doesn't change. It can be tested with "-> string" (where only the "returned elements" tab is not empty).

Improve JS performance by storing length before comparing to it in loops
Since https://github.com/rust-lang/rust/pull/79052 is quite complicated to review, I suggested to split into smaller parts. This first part is mostly about saving the array length into a variable (I tried to not change anything else as much as possible 😃 ).

More js cleanup
Part of #79052 (Same kind as #80515).
This one is about some small fixes:
* Replacing some loops with `onEachLazy`.
* Removing unused function arguments.
* Turn `buildHelperPopup` into a variable so it can be "replaced" once the function has been called once so it's not called again.

Rustdoc: only report broken ref-style links once
This PR assigns the markdown `LinkType` to each parsed link and passes this information into the link collector.
If a link can't be resolved in `resolve_with_disambiguator`, the failure is cached for the link types where we only want to report the error once (namely `Shortcut` and `Reference`).
Fixes #77681
Add suggestion for "ignore" doc code block
Part of https://github.com/rust-lang/rust/issues/30032.
This PR adds a suggestion to help users when they have a "ignore" doc code block which is invalid rust code.
