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>:
```
{
file_name: {
file_name: '/home/imperio/rust/rust/src/test/rustdoc-gui/type-declation-overflow.goml',
output: 'type-declation-overflow... FAILED\n' +
'...'
},
output: Error: expected `runTest` first argument to be a string

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

specialize impl of `ToString` on `bool`
Fixes#106611
Specialize `bool`s `ToString` impl by copying it from `Display`. This is a significant optimization as we avoid lots of dynamic dispatch. AFAIK, this doesn't require a API Change Proposal as this doesn't regress existing code and can be undone without regressing code.
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.
Consider return type when giving various method suggestions
1. Fix a bug in method probe where we weren't normalizing `xform_ret_ty` for non-`impl` method candidates. This shouldn't affect happy-path code, since we only use `xform_ret_ty` when probing methods for diagnostics (I think).
2. Pass the return type expectation down to `lookup_probe`/`probe_for_name` usages in diagnostics. Added a few UI tests to gate against bad suggestions.
3. Make a `FnCtxt::lookup_probe_for_diagnostic` which properly passes down `IsSuggestion(true)`. Should help suppress other weird notes in some corner cases.

update test for inductive canonical cycles
the previous test always resulted in a cycle 😅 cc https://github.com/rust-lang/chalk/pull/787.
I checked with #102713 and this is the only test which fails with that PR.

Accept old spelling of Fuchsia target triples
The old spelling of Fuchsia target triples was changed in #106429 to add a proper vendor. Because the old spelling is widely used, some projects may need time to migrate their uses to the new triple spelling. The old spelling may eventually be removed altogether.

Revert "bootstrap: Get rid of `tail_args` in `stream_cargo`"
This reverts commit 9dfe50440e. (Note: that merged as part of https://github.com/rust-lang/rust/pull/106305, but https://github.com/rust-lang/rust/pull/106305/ contains more commits than just 9dfe50440e6d48bd2fd40a4b7b3992998e55eace.)
Fixes `x clippy`. It turns out `clippy` was the only one using `tail_args` 🤦 sorry for not testing this earlier.

Fix bad import suggestion with nested `use` tree
Fixes#105566Fixes#105373
Ideally, we'd find some way to turn these into structured suggestions -- perhaps on a separate line as a different `use` statement, but I have no idea how to access the span for the whole `use` from this point in the import resolution code.
