Fix reexport of `doc(hidden)` item
Part of #59368.
It doesn't fix the `doc(inline)` nor the `doc(hidden)` on macro. I'll do it in a follow-up PR.
r? `@notriddle`
This is useful for rust-lang/rust to allow setting a sysroot that's
*only* for build scripts, different from the regular sysroot passed in
RUSTFLAGS (since cargo doesn't apply RUSTFLAGS to build scripts or
proc-macros).
That said, the exact motivation is not particularly important: this
fixes a regression from
https://github.com/rust-lang/rust-clippy/pull/9881/commits/5907e9155ed7f1312d108aa2110853472da3b029#r1060215684.
Note that only RUSTFLAGS is tested in the new integration test; passing
--sysroot through `clippy-driver` never worked as far as I can tell, and
no one is using it, so I didn't fix it here.
remove unreachable error code `E0490`
AFAIK, the untested and undocumented error code `E0490` is now unreachable, it was from the days of the original borrow checker.

Harden the pre-tyctxt query system against accidental recomputation
While the current compiler has no issues where we `take` and then compute the query again, in https://github.com/rust-lang/rust/pull/105462 I accidentally introduced such a case.
I also took the opportunity to remove `peek_mut`, which is only ever used for `global_tcx` to then invoke `enter`. I added an `enter` method directly on the query.

Stabilize `::{core,std}::pin::pin!`
As discussed [over here](https://github.com/rust-lang/rust/issues/93178#issuecomment-1295843548), it looks like a decent time to stabilize the `pin!` macro.
### Public API
```rust
// in module `core::pin`
/// API: `fn pin<T>($value: T) -> Pin<&'local mut T>`
pub macro pin($value:expr $(,)?) {
…
}
```
- Tracking issue: #93178
(now all this needs is an FCP by the proper team?)
Revert "warn newer available version of the x tool"
Reverts rust-lang/rust#104552
Running the x executable directly created an [issue](https://github.com/rust-lang/rust/issues/106469) here. There are other options for warning a user that a newer version of x exists in the issue's discussion as well.

Use CI LLVM in `test-various` builder
It was disabled because it needs `lld`, but since #104748 was merged it is no longer needed.
This will speed this test, since it no longer needs to build LLVM.
Fix scrolling for item declaration block
Fixes https://github.com/rust-lang/rust/issues/105580.
The `contain: layout` was the issue here and the bug was actually on both mobile and desktop.

Fix invalid files array re-creation in rustdoc-gui tester
It fixes the error <code>expected `runTest` first argument to be a string</code>:
```

output: 'type-declation-overflow... FAILED\n' +

The problem was that I concatenated two arrays of object whereas `files` is supposed to be an array of string.

Fix help docs for -Zallow-features
The arguments for -Zallow-features are comma-separated (`parse_opt_comma_list`), not space separated (`parse_list`).
[RFC 2397] Initial implementation
cc #51992
Because of previous experiences where ppl didn't have the time to review large PRs (or any at all), the implementation of this feature will be delivered in small chunks to hopefully make things faster.
In this initial PR, only the attribute is being declared and gated with ordinary tests.
Remove unneeded ItemId::Primitive variant
As I mentioned [here](https://github.com/rust-lang/rust/pull/106412#issuecomment-1371405115), I wondered if `ItemId::Primitive` was actually used for anything. Apparently, it seems so because removing it led to no changes as far as I and tests could see.

remove E0280
After looking at #61137 I tried my hand at E0280. I'm unable to find a reasonable example that emits the error. There are a couple of old examples that compile with the current compiler ([#26217](https://github.com/rust-lang/rust/issues/26217), [#42114](https://github.com/rust-lang/rust/issues/42114), [#27113](https://github.com/rust-lang/rust/issues/27113)) and there is a [bug with chalk](b7cdb635c4/src/test/ui/chalkify/bugs/async.rs) that makes it emit the error, with a couple more chalk bugs on zulip.
It seems like the error is supposed to be emitted from unfulfilled where bounds, of which two are related to borrow checking (error in where T: 'a or where 'a: 'b) and thus tend to emit errors like "lifetime may not live long enough" from borrow checking instead. The final case is with type equality constraints (where <T as Iterator>::Item == u32), which is unimplemented ([#20041](https://github.com/rust-lang/rust/issues/20041)). That such different problems are supposed to have the same error code also seems strange to me.
Since the error seems to only be emitted when using chalk I propose to remove it and replace it with an ICE instead. A crater run might be warranted.
Pinging `@jackh726` due to removal of chalk test that now ICEs.
