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.

- Either explicitly annotate `let x: () = expr;` where `x` has unit
type, or remove the unit binding to leave only `expr;` instead.
- Fix disjoint-capture-in-same-closure test
To reproduce the changes in this commit locally:
- Run `./x test tidy` and remove all the output files not associated
with a test file anymore, as reported by tidy.
- Run `./x test tests/mir-opt --bless` to generate the new outputs.
It might happen that a synthetic target name does not match one of the
hardcoded ones in std's build script, causing std to fail to build. This
commit changes the std build script avoid including the restricted-std
feature unconditionally when a synthetic target is being built.
Some targets are added to these hashmaps at runtime, and are not present
during dry runs. To avoid errors, this commit changes all the related
functions to always return empty strings/paths during dry runs.
Dont compute `opt_suggest_box_span` span for TAIT
Fixes#112434
Also a couple more commits on top, pruning some dead code and fixing another weird suggestion encountered in the above issue.
This has real differences in the effective debuginfo: in particular, it omits the module-level information and breaks perf.
Allow passing `line-tables-only` directly in config.toml instead.
rustdoc: Add `item_template` macro
Closes#112021
This change removes the use of `self.borrows()` in Askama templates, removes code duplication from `item_and_mut_cx()`, and improved readability by eliminating the prefix `item_template_` when calling from the template.
