SIMD-style optimizations are the most common use for `[T]::align_to(_mut)`, but that's `unsafe`. So these are *safe* wrappers around it, now that we have the `Simd` type available, to make it easier to use.
```rust
impl [T] {
pub fn as_simd<const LANES: usize>(&self) -> (&[T], &[Simd<T, LANES>], &[T]);
pub fn as_simd_mut<const LANES: usize>(&mut self) -> (&mut [T], &mut [Simd<T, LANES>], &mut [T]);
}
```
…ignment, r=jackh726,pnkfelix Stabilize `destructuring_assignment` Closes rust-lang#71126 - [Stabilization report](rust-lang#71126 (comment)) - [Completed FCP](rust-lang#71126 (comment)) `@rustbot` label +F-destructuring-assignment +T-lang Also needs +relnotes but I don't have permission to add that tag.

Add `[T]::as_simd(_mut)`

They're `cfg`'d out for miri because the `simd` module as a whole is unavailable there.
…tester-code, r=jsha Improve code for rustdoc-gui tester Following advice given in rust-lang#91391. It nicely improves the code readability. :) r? `@jsha`
core: minor `Option` doc correction
Handle unordered const/ty generics for object lifetime defaults *feel like I should have a PR description but cant think of what to put here* r? ```@lcnr```
…ebar, r=jsha Fix source code page sidebar on mobile Current broken behaviour: https://user-images.githubusercontent.com/3050060/145984316-35c82353-5bab-4dc6-9ac6-63ea7e5c27d8.mp4 Fixed: https://user-images.githubusercontent.com/3050060/145984329-8be1127b-d707-424d-ac3c-c1fb3c48a093.mp4 r? `@jsha`
…es_library_proc_macro, r=petrochenkov Removed `in_band_lifetimes` from `library\proc_macro` Issue [rust-lang#91867](rust-lang#91867) This is my first try, I followed the instructions given. Fixed all the errors that were thrown while compiling. Compiled with stage 0,1, and 2 all of them compiled successfully.
