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]);
}
```

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

They're `cfg`'d out for miri because the `simd` module as a whole is unavailable there.

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``
…stc_symbol_mangling, r=jackh726 Remove `in_band_lifetimes` from `rustc_symbol_mangling` Helping out with rust-lang#91867
Fix a bunch of typos I hope that none of these files is not supposed to be modified. FYI, I opened separate PRs for typos in submodules, in the respective repositories * rust-lang/stdarch#1267 * rust-lang/backtrace-rs#455
…-constification-begins, r=oli-obk
Constify `bool::then{,_some}`
Note on `~const Drop`: it has no effect when called from runtime functions, when called from const contexts, the trait system ensures that the type can be dropped in const contexts.
