rust-lang/portable-simd#273: Documentation update for reduce functions, swizzle
Working through giving example documentation to every Simd function.

The major change in this patch is using doc macros to generate
type-specific examples for each function, using a visually-apparent type
constructor. This makes it feel nicer to have twelve separate
documentation entries for reduce_product(), for example.

rust-lang/portable-simd#265: Move comparisons to traits
A simpler variant of rust-lang/portable-simd#206.

* Comparisons are moved to `SimdPartialEq`, `SimdPartialOrd`, and `SimdOrd`.  The function names are prefixed with `simd_` to disambiguate from the regular `PartialEq` etc functions.  With the functions on traits instead of `Simd` directly, shadowing the function names doesn't work very well.
* Floating point `Ord`-like functions are put into a `SimdFloat` trait.  The intention is that eventually (some time after this PR) all floating point functions will be moved from `Simd` to `SimdFloat`, and the same goes for future `SimdInt`/`SimdUint` traits.

rust-lang/portable-simd#248: Remove default features
Now that we are thoroughly embedded in libcore, we don't need these on by default.

rust-lang/portable-simd#239: Bitmask conversion trait
Another approach that fixes rust-lang/portable-simd#223, as an alternative to rust-lang/portable-simd#238.

This adds the `ToBitMask` trait, which is implemented on a vector for each bitmask type it supports.  This includes all unsigned integers with enough bits to contain it.  The byte array variant has been separated out for now into rust-lang/portable-simd#246 and still requires `generic_const_exprs`, but the integer variants no longer require it and can make it to nightly.

rust-lang/portable-simd#245: Explain unsafe contracts of core::simd
* Explain unsafe contracts of core::simd

This permeates the module with remarks on safety for pub methods,
layout of the Simd type, correct use of intrinsics, et cetera.
This is mostly to help others curious about how core::simd works,
including other Rust contributors, `unsafe` library authors,
and eventually ourselves.

09fa72ae84 Merge portable-simd#219 - ./std-float
impl std::simd::StdFloat

 This introduces an extension trait to allow use of floating point methods
 that need runtime support. It is *excessively* documented because its mere
 existence is quite vexing, as the entire thing constitutes a leakage of
 implementation details into user observable space. Eventually the entire
 thing will ideally be folded into core and restructured to match the rest
 of the library, whatever that structure might look like at the time. This
 is preferred in lieu of the "lang item" path because any energy the lang
 items require (and it will be significant, by Simulacrum's estimation) is
 better spent on implementing our libmvec.
