* Instead uses `before` and `after` variable names in the example
where `greater` and `lesser` are flipped.
* Uses `<=` and `>=` instead of "less than or equal to" and "greater
than or equal to" to make the docs more concise.
* General attempt to remove unnecessary words and be more precise. For
example it seems slightly wrong to say "its final sorted position",
since this implies there is only one sorted position for this element.

Unsafe binder support in rustdoc
Adds rustdoc support for unsafe binder types: `unsafe<'a> Foo<'a>`. Doesn't add json support yet.

Use python built in type annotations in LLDB visualizer scripts
Replaces type annotation comments with python's built-in type annotations.
Built-in type annotations were added in python 3.5. LLDB [currently recommends (and as of LLVM 21, will enforce)](https://github.com/llvm/llvm-project/pull/114807) a minimum python version of 3.8. Rust's test suite also requires python 3.10.

compiler: Add a statement-of-intent to `rustc_abi`
This just documents the most basic idea of what the crate is even for in my view, rather than leaving that strewn about GitHub issues, PR reviews, and Zulip streams. In particular, I hope to make it clearer what code should go in `rustc_abi` and what should not, which is of immediate relevance to contributors.
I considered going even further and explaining ideas like "ABI compatibility", prologues, and so on. However, because of the cross-cutting nature of ABI, I think such explanations should probably live in the place for cross-cutting documents: the rustc dev guide. This is only meant to be a quick "by the way".
explicitly set float ABI for all ARM targets
We currently always set the `FloatABIType` field in the LLVM target machine to `Default`, which means LLVM infers the ARM float ABI (hard vs soft) from the LLVM target triple. This causes problems such as having to set the LLVM triple to `*-gnueabi` for our `musleabi` targets to ensure they get correctly inferred as soft-float targets. It also means rustc doesn't really know which float ABI ends up being used, which is a blocker for https://github.com/rust-lang/rust/pull/134794. So I think we should stop doing that and instead explicitly control that value. That's what this PR implements.
See [Zulip](https://rust-lang.zulipchat.com/#narrow/channel/187780-t-compiler.2Fwg-llvm/topic/Softfloat.20ABI.2C.20hardfloat.20instructions) for more context.
Best reviewed commit-by-commit. I hope I got all those `llvm_floatabi` values right...
ptr docs: make it clear that we are talking only about memory accesses
This should make it harder to take this sentence out of context and misunderstand it.
Stabilize `style_edition = "2024"` in-tree
This PR stabilizes the `style_edition` flag in rustfmt.
**Why am I doing this in-tree?** The beta release cut is imminent (according to forge, on January 3) and this is the most lightweight approach to getting this flag stable on nightly. It's imperative (as far as I can tell -- `@traviscross` can verify or disagree) that we stabilize the `style_edition` flag so that users can control their style edition separately from the edition.
I'm happy to move this PR to the rustfmt repo and subsequently prepare a subtree sync if someone on `@rust-lang/rustfmt` believes that we should get this landed on the rustfmt side then synced. If this is the right recourse, I'd like to note that this is still quite time-sensitive. However, I'm happy to dedicate time to get this done if necessary, since I'd really like to un-jeopardize the style edition.

stabilize const_swap
libs-api FCP passed in https://github.com/rust-lang/rust/issues/83163.
However, I only just realized that this actually involves an intrinsic. The intrinsic could be implemented entirely with existing stable const functionality, but we choose to make it a primitive to be able to detect more UB. So nominating for `@rust-lang/lang` to make sure they are aware; I leave it up to them whether they want to FCP this.
While at it I also renamed the intrinsic to make the "nonoverlapping" constraint more clear.
Fixes#83163
ci: Cleanup docker build logs in CI
Cleaning up the CI logs to make reviewing CI failures easier. This PR adds a `::group` around the docker tag hash input which is pretty large (250+ lines) and is probably not relevant for most people.

Add illumos target documentation
Fixes https://github.com/rust-lang/rust/pull/130132#issuecomment-2339055221
`@jclulow` `@pfmooney` I'm adding you as requested.
The page is very barebones (as I do not know illumos well) and could use some improvements (for example in the "Cross-compilation toolchains and C code" section).
Feel free to suggest improvements (or rewrite it from scratch) if you find something.
A couple datalog/borrowck cleanups
As discussed on zulip, here's a chill one in between slightly more interesting PRs:
- I hadn't noticed there still were a couple of datalog-related modules outside of their dedicated `polonius` module (go to horn-clause jail, bonk!).
- there somehow was both a `diags` module and a `diagnostics` module.
- a couple other tiny things being renamed -- let me know what you think.
As requested I've tried to have somewhat granular commits to ease review, but the last two or three could be squashed together, since they're all related to the `diags` module (but moving its contents is less tedious to check in its own commit).
