Add `select_unpredictable` to force LLVM to use CMOV
Since https://reviews.llvm.org/D118118, LLVM will no longer turn CMOVs into branches if it comes from a `select` marked with an `unpredictable` metadata attribute.
This PR introduces `core::intrinsics::select_unpredictable` which emits such a `select` and uses it in the implementation of `binary_search_by`.

[rustdoc] Make the buttons remain when code example is clicked
Follow-up of https://github.com/rust-lang/rust/pull/125779.
One current issue we have with "run" button and the newly added copy code button is that if you're on mobile devices, you can't use them. I took a look at how `mdbook` is handling it and when you click on a code example, they show the buttons. I think it's a really good idea as if you want to copy the code on your mobile device, you will click on it, showing the buttons.
Feature can be tested [here](https://rustdoc.crud.net/imperio/click-code-example/foo/struct.Bar.html).

Set branch protection function attributes
Since LLVM 19, it is necessary to set not only module flags, but also function attributes for branch protection on aarch64. See https://github.com/llvm/llvm-project/commit/e15d67cfc2e5775cc79281aa860f3ad3be628f39 for the relevant LLVM change.
Fixes https://github.com/rust-lang/rust/issues/127829.

elaborate unknowable goals
A reimplemented version of #124532 affecting only the new solver. Always trying to prove super traits ends up causing a fatal overflow error in diesel, so we cannot land this in the old solver.
The following test currently does not pass coherence:
```rust
trait Super {}
trait Sub<T>: Super {}
trait Overlap<T> {}
impl<T, U: Sub<T>> Overlap<T> for U {}
impl<T> Overlap<T> for () {}
fn main() {}
```
We check whether `(): Sub<?t>` holds. This stalls with ambiguity as downstream crates may add an impl for `(): Sub<Local>`. However, its super trait bound `(): Super` cannot be implemented downstream, so this one is known not to hold.
By trying to prove that all the super bounds of a trait before adding a coherence unknowable candidate, this compiles. This is necessary to prevent breakage from enabling `-Znext-solver=coherence` (#121848), see tests/ui/coherence/super-traits/super-trait-knowable-2.rs for more details. The idea is that while there may be an impl of the trait itself we don't know about, if we're able to prove that a super trait is definitely not implemented, then that impl would also never apply/not be well-formed.
This approach is different from #124532 as it allows tests/ui/coherence/super-traits/super-trait-knowable-3.rs to compile. The approach in #124532 only elaborating the root obligations while this approach tries it for all unknowable trait goals.

Optimize empty case in Vec::retain
While profiling some code that happens to call Vec::retain() in a tight loop, I noticed more runtime than expected in retain, even in a bench case where the vector was always empty. When I wrapped my call to retain in `if !myvec.is_empty()` I saw faster execution compared with doing retain on an empty vector.
On closer inspection, Vec::retain is doing set_len(0) on itself even when the vector is empty, and then resetting the length again in BackshiftOnDrop::drop.
Unscientific screengrab of a flamegraph illustrating how we end up spending time in set_len and drop:

Stabilize offset_of_nested
Tracking issue #120140. Closes #120140.
As the FCP is now nearing its end I have opened a stabilization PR. I have done this separately to the offset_of_enum feature, since that FCP has not started.

Stop using `MoveDataParamEnv` for places that don't need a param-env
I think not threading through a `ParamEnv` makes it clearer that these functions don't do anything particularly "type systems"-y.

rustdoc: word wrap CamelCase in the item list table and sidebar
This is an alternative to https://github.com/rust-lang/rust/pull/126209. That is, it fixes the issue that affects the very long type names in https://docs.rs/async-stripe/0.31.0/stripe/index.html#structs.
This is, necessarily, a pile of nasty heuristics. We need to balance a few issues:
- Sometimes, there's no real word break. For example, `BTreeMap` should be `BTree<wbr>Map`, not `B<wbr>Tree<wbr>Map`.
- Sometimes, there's a legit word break, but the name is tiny and the HTML overhead isn't worth it. For example, if we're typesetting `TyCtx`, writing `Ty<wbr>Ctx` would have an HTML overhead of 50%. Line breaking inside it makes no sense.

skip assoc type during infer source visitor
Fixes #121613
Due to the generic arguments being lost during normalization, the associated type cannot retrieve the correct generics information, so this PR follows this [comment](https://github.com/rust-lang/rust/blob/master/compiler/rustc_trait_selection/src/error_reporting/infer/need_type_info.rs#L937-L942) and skips `DefKind::AssocTy`

Tell users not to file a bug when using internal library features
Actually fixes #97501. I don't think we should suppress the suggestion to add `#![feature(..)]`, though I guess I could be convinced otherwise.

Didn't add a test b/c I don't think we test this for lang features either, but I can confirm it does work.

Don't record trait aliases as marker traits
Don't record `#[marker]` on trait aliases, since we use that to check for the (non-presence of) associated types and other things which don't make sense of trait aliases. We already enforce this attr is only applied to a trait.
Also do the same for `#[const_trait]`, which we also enforce is only applied to a trait. This is a drive-by change, but also worthwhile just in case.
Fixes #127222

Don't elaborate associated types with Sized bounds in `trait_object_ty` in cfi
The elaboration mechanism introduced in #123005 didn't filter for associated types with `Self: Sized` bounds, which since #112319 has excluded them from the object type.
Fixes #127881

This is an alternative to ee6459d6521cf6a4c2e08b6e13ce3c6ce5d55ed0.
That is, it fixes the issue that affects the very long type names
in https://docs.rs/async-stripe/0.31.0/stripe/index.html#structs.
This is, necessarily, a pile of nasty heuristics.
We need to balance a few issues:
- Sometimes, there's no real word break.
For example, `BTreeMap` should be `BTree<wbr>Map`,
not `B<wbr>Tree<wbr>Map`.
- Sometimes, there's a legit word break,
but the name is tiny and the HTML overhead isn't worth it.
For example, if we're typesetting `TyCtx`,
writing `Ty<wbr>Ctx` would have an HTML overhead of 50%.
Line breaking inside it makes no sense.

Perform instsimplify before inline to eliminate some trivial calls
I am currently working on #128081. In the current pipeline, we can get the following clone statements ([godbolt](https://rust.godbolt.org/z/931316fhP)):
```
bb0: {
StorageLive(_2);
_2 = ((*_1).0: i32);
StorageLive(_3);
_3 = ((*_1).1: u64);
_0 = Foo { a: move _2, b: move _3 };
StorageDead(_3);
StorageDead(_2);
return;
}
```
Analyzing such statements will be simple and fast. We don't need to consider branches or some interfering statements. However, this requires us to run `InstSimplify`, `ReferencePropagation`, and `SimplifyCFG` at least once. I can introduce a new pass, but I think the best place for it would be within `InstSimplify`.
I put `InstSimplify` before `Inline`, which takes some of the burden away from `Inline`.
