Adjust UI tests for `unit_bindings` lint
- Explicitly annotate `let x: () = expr;` where `x` has unit type, or remove the unit binding to leave only `expr;` instead.
- Use `let () = init;` or `let pat = ();` where appropriate.
- Fix disjoint-capture-in-same-closure test which wasn't actually testing a closure: `tests/ui/closures/2229_closure_analysis/run_pass/disjoint-capture-in-same-closure.rs`.
Note that unfortunately there's *a lot* of UI tests, there are a couple of places where I may have left something like `let (): ()` (this is not needed but is left over from an ealier version of the lint) which is bad style.
This PR is to help with the `unit_bindings` lint at #112380.
It fixes the following error:
error[E0412]: cannot find type `sockcred2` in module `libc`

loongarch64-unknown-none*: Set default relocation model to static
This PR sets the default relocation model to `static` for `loongarch64-unknown-none*` targets. This change aims to streamline the development of the bare-metal project by removing the need for the executable program loader to implement relocation.
Make BinaryHeap parametric over Allocator
Tracking issue: #32838
Related: https://github.com/rust-lang/wg-allocators/issues/7
This parametrizes `BinaryHeap` with `A`, similarly to how other collections are parametrized.
A couple things I left out:
```
BinaryHeap::append
Currently requires both structures to have the same allocator type. Could
change, but depends on Vec::append, which has the same constraints.
impl<T: Ord> Default for BinaryHeap<T>
Not parametrized, because there's nowhere to conjure the allocator from.
impl<T: Ord> FromIterator<T> for BinaryHeap<T>
Not parametrized, because there's nowhere to conjure the allocator from.
impl<T: Ord, const N: usize> From<[T; N]> for BinaryHeap<T>
Not parametrized, because there's nowhere to conjure the allocator from.
unsafe impl<I> AsVecIntoIter for IntoIter<I>
AsVecIntoIter is not allocator aware, and I didn't dare change it without guidance. Is this something important?
```
I've seen very few tests for allocator_api in general, but I'd like to at least test this on some usage code in my projects before moving forward.
EDIT: Updated the list of impls and functions that are not affected by this. `BinaryHeap` no longer has a `SpecExtend` impl, and prior work made implementing `Extend` possible.
This feature extends rustdoc to support the syntax that most users will
naturally attempt to use to search for diverging functions.
Part of #60485
It's already possible to do this search with `primitive:never`, but
that's not what the Rust language itself uses, so nobody will try it if
they aren't told or helped along.
- Create `Answer` type that is not just a type alias of `Result`
- Remove a usage of `map_layouts` to make the code easier to read
- Don't hide errors related to Unknown Layout when computing transmutability

Add windows_sys type definitions for ARM32 manually
`windows_sys` bindings do not include platform-specific type definitions for ARM 32 architecture, so it breaks `thumbv7a-pc-windows-msvc` and `thumbv7a-uwp-windows-msvc` targets. This PR tries to add them back by manually inserting them together with the generated ones.
`WSADATA` is copied from the generated definition for `x86`. `CONTEXT` is copied from the definition before `windows_sys` is introduced (which is just an empty enum): 4a18324a4d/library/std/src/sys/windows/c.rs (L802).
Fixes#112265.

implement stdout streaming in `render_tests::Renderer`
This way, we can show the test dot characters on the console immediately, without having to wait for the entire line to finish.
