Relax implicit `T: Sized` bounds on `BufReader<T>`, `BufWriter<T>` and `LineWriter<T>`
TL;DR:
```diff,rust
-pub struct BufReader<R> { /* ... */ }
+pub struct BufReader<R: ?Sized> { /* ... */ }
-pub struct BufWriter<W: Write> { /* ... */ }
+pub struct BufWriter<W: ?Sized + Write> { /* ... */ }
-pub struct LineWriter<W: Write> { /* ... */ }
+pub struct LineWriter<W: ?Sized + Write> { /* ... */ }
```
This allows using `&mut BufReader<dyn Read>`, for example.
**This is an insta-stable change**.
std: available_parallelism using native netbsd api first before falling back to existing code paths like FreeBSD does.
…t, r=compiler-errors Support 128-bit enum variant in debuginfo codegen fixes rust-lang#111600
`#[lang_item]` for `core::ptr::Unique`
Tree Borrows is about to introduce experimental special handling of `core::ptr::Unique` in Miri to give it a semantics.
As of now there does not seem to be a clean way (i.e. other than `&format!("{adt:?}") == "std::ptr::Unique"`) to check if an `AdtDef` represents a `Unique`.

Draft: making a lang item
…lause, r=lcnr Make assumption functions in new solver take `Binder<'tcx, Clause<'tcx>>` We just use an if-let to match on an optional clause at all the places where we transition from `Predicate` -> `Clause`, but I assume that when things like item-bounds and param-env start to only store `Clause`s then those can just be trivially dropped. r? ``@lcnr``
… r=wesleywiser Disable alignment checks on i686-pc-windows-msvc r? `@wesleywiser` Because you were in the Zulip discussion of this: https://rust-lang.zulipchat.com/#narrow/stream/238009-t-compiler.2Fmeetings/topic/.5Bweekly.5D.202023-06-15 cc rust-lang#112480
…t, r=petrochenkov Add `SyntaxContext::is_root` Makes the code a tad nicer.
