cg_llvm: Rename `OperandBundleOwned` to `OperandBundleBox`
As with `DIBuilderBox`, the "Box" suffix does a better job of communicating that this is an owning pointer to some borrowable resource.
This also renames the `raw` method to `as_ref`, which is what it would have been named originally if the `Deref` problem (#137603) had been known at the time.
No functional change.

Remove mono item collection strategy override from -Zprint-mono-items
Previously `-Zprint-mono-items` would override the mono item collection
strategy. When debugging one doesn't want to change the behaviour, so
this was counter productive. Additionally, the produced behaviour was
artificial and might never arise without using the option in the first
place (`-Zprint-mono-items=eager` without `-Clink-dead-code`). Finally,
the option was incorrectly marked as `UNTRACKED`.
Resolve those issues, by turning `-Zprint-mono-items` into a boolean
flag that prints results of mono item collection without changing the
behaviour of mono item collection.
For codegen-units test incorporate `-Zprint-mono-items` flag directly
into compiletest tool.
Test changes are mechanical. `-Zprint-mono-items=lazy` was removed
without additional changes, and `-Zprint-mono-items=eager` was turned
into `-Clink-dead-code`. Linking dead code disables internalization, so
tests have been updated accordingly.

Update miniz_oxide dependency of coverage_dump
This was the final subproject that depended on ```miniz_oxide``` 0.7.x after the rest were when updating the ```backtrace-rs``` dependency in in #140705. Older versions of ```miniz_oxide``` got hit by a [serious](https://github.com/rust-lang/rust/issues/132636) performance regression in rust 1.82 (which has been worked around in more recent versions of the library) so should really be avoided if possible (granted it only affects compression so not sure if it had much impact in practice here, though there have also been some other performance improvements since .)
This also means no longer having to build two versions of miniz_oxide as everything can now use the same version, and no longer needing to build both ```adler``` and ```adler2```

Async drop fix for async_drop_in_place<T> layout for unspecified T
Fix for https://github.com/rust-lang/rust/issues/140423.
Layout of `async_drop_in_place<T>::{closure}` is calculated for unspecified T from dataflow_const_prop `try_make_constant`.
`@oli-obk,` do you think, it may be a better solution to add check like `if !args[0].is_fully_specialized() { return None; }` in `fn async_drop_coroutine_layout`?
And could you, pls, recommend, how to implement `is_fully_specialized()` in a most simple way?

Add T-compiler backports Zulip notifications
This patch make it so, that the triagebot willl send notifications to the Zulip channel [#t-compiler/backports](https://rust-lang.zulipchat.com/#narrow/channel/474880-t-compiler.2Fbackports) when a label `{stable-beta}-nominated` is added to beta or stable backport pull request. Requirement to trigger this notification is that the pull request be labeled `T-compiler`.
Note: Zulip notifications can send notifications also on other events (`message_on_close` and `message_on_reopen`) but I omitted them for now, I am not yet sure we need them.

test intrinsic fallback bodies with Miri
`@Urgau` noted in https://github.com/rust-lang/rust/pull/140792 that fallback bodies our backends don't use are untested... which is correct, and it is a problem. So this adds a testing-only flag to Miri to force the use of fallback bodies, and adds a run of the Miri test suite with that flag to CI. This should not take much more than a minute so I hope it's fine? Let's see how long it actually takes.
While at it, I made that test run also enable MIR optimizations. Miri's CI has a run with that, and it has caught mir-opt bugs in the past -- this way we'd see the CI failure earlier.

Prefer to suggest stable candidates rather than unstable ones
Fixes #140240
The logic is to replace unstable suggestions if we meet a new stable one, and do nothing if any other situation. In old logic, we just use the first candidate we meet as the suggestion for the same items.
E.g., `std::range::legacy::Range` vs `std::ops::Range`, `legacy` in the former is unstable, we prefer to suggest use the latter.

Use intrinsics for `{f16,f32,f64,f128}::{minimum,maximum}` operations
This PR creates intrinsics for `{f16,f32,f64,f64}::{minimum,maximum}` operations.
This wasn't done when those operations were added as the LLVM support was too weak but now that LLVM has libcalls for unsupported platforms we can finally use them.
Cranelift and GCC[^1] support are partial, Cranelift doesn't support `f16` and `f128`, while GCC doesn't support `f16`.

1.87.0 release notes: remove nonsensical `~` operator
There is no `~` unary prefix operator, and it definitely shouldn't be in the release notes for a feature whose introducing PR doesn't test for it (because it doesn't exist). Also fix an unnecessary `}` on the same line.

remove 'unordered' atomic intrinsics
As their doc comment already indicates, these operations do not currently have a place in our memory model. The intrinsics were introduced to support a hack in compiler-builtins, but that hack recently got removed (see https://github.com/rust-lang/compiler-builtins/issues/788).

remove intrinsics::drop_in_place
This was only ever accidentally stable, and has been marked as deprecated since Rust 1.52, released almost 4 years ago. We've removed the old serialization `derive`s, maybe we can remove this one as well?
As suggested by ``@jhpratt,`` let's see what crater says for this one.

rustdoc: add a handle that makes sidebar resizing more obvious
This aims to make the resizable sidebars more obvious
Preview: <https://notriddle.com/rustdoc-html-demo-12/sidebar-resize-handle/std/index.html>
This change is based on some discussion on [lolbinarycat's idea], but with a more "traditional" design. Specifically, while very few systems use exactly this design, most of them use [a skeumorph](https://ux.stackexchange.com/questions/80463/what-do-the-3-close-horizontal-bars-not-hamburger-menu-represent-and-what-is-t/80591#80591) of a grip texture:
- This design is similar to the one used in the Rust Playground, and almost identical to UX StackExchange:
<details><img src="https://github.com/user-attachments/assets/39a6bb69-4895-4fd0-87da-b87913bc7309"></details>
<details><img src="https://github.com/user-attachments/assets/a41942e1-651b-410b-b855-2aafe8fe54f4"></details>
- In Jira, resizable sidebars have a stack of four dots, but only in one row.
<details><img src="https://github.com/user-attachments/assets/13047998-02bf-47e6-b796-16f393f870b0"></details>
- In The GIMP, resizable sidebars have a stack of three dots.
<details><img src="https://github.com/user-attachments/assets/138f5c21-3069-4bbe-b306-0bb9a4bf0318"></details>
- In [old Windows], "panes" are defined to have the same border style as a window, which has a raised appearance. To evoke this, the PR adds a lightweight "shadow" border, darker than the sidebar itself
<details><img src="https://github.com/user-attachments/assets/301da4b8-6c48-4131-b741-1689af84670a"></details>
- In [NeXT], a drag point usually had an innie, whether the line in a slider or the circle in a scroller; I can also hide and show the favorites bar in Workspace by dragging on a circular "grip spot"
<details><img src="https://github.com/user-attachments/assets/b13c2d30-a3a8-4672-90fa-58c1fdf19f42"></details>
- In [old Mac], drag handles for things usually had a "grip track" of parallel lines.
<details><img src="https://github.com/user-attachments/assets/1fbecc67-ffbc-4ed6-a8c5-a9ff085638db"></details>
*This design is far closer to old Mac than anything else*, though they've put it in the bottom corner instead of the middle.
- [OSX] kept that, but the "Source List" part of the Finder still had the circle grip for a time the same way Workspace did (resulting in an odd mishmash, if you compare the source list sidebar with the other grip tracks embedded in the scrollbars).
<details><img src="https://github.com/user-attachments/assets/551b8f9d-2dd8-4291-917f-dc88741a2b97"></details>

Merge typeck loop with static/const item eval loop
r? `@ghost`
Let's try a small one first. Doing this in general has some bad cache coherence issues because the query caches are laid out in `Vec<QueryResult>` lists per query where each index refers to a `DefId` in the same order as we're iterating. Iterating two or more lists at the same time does have cache issues, so I want to poke a bit at it to see if we can't merge just a few of them at a time.

|

It's a "utility trait to reduce boilerplate" implemented for `P` and
`AstNodeWrapper`, but removing it gives a net reduction of twenty lines
of code. It's also simpler to just implement
`HasNodeId`/`HasAttrs`/`HasTokens` directly on types instead of via
`AstDeref`.
(I decided to make this change when doing some related refactoring and
the error messages involving `AstDeref` and `HasAttrs` were hard to
understand; removing it helped a lot.)
