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#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.

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.

ecc00efee0 impl std::simd::StdFloat
While consulting with Simulacrum on how to make available the float
functions that currently require runtime support for `Simd<f32, N>` and
`Simd<f64, N>`, we realized breaking coherence with the classic approach
of lang items was, since `{core,std}::simd::Simd` is a `ty::Adt`, likely
to be quite a bit nasty. The project group has a long-term plan for how
to get around this kind of issue and move the associated functions into
libcore, but that will likely take time as well. Since all routes
forward are temporally costly, we probably will skip the lang item
approach entirely and go the "proper" route, but in the interests of
having something this year for people to play around with, this
extension trait was whipped up.

For now, while it involves a lot of fairly internal details most users
shouldn't have to care about, I went ahead and fully documented the
situation for any passerby to read on the trait, as the situation is
quite unusual and puzzling to begin with.

Merge portable-simd#210 - ./wrap-shifts
Refactor ops.rs with wrapping shifts

This approaches reducing macro nesting in a slightly different way. Instead of just flattening details, make one macro apply another. This allows specifying all details up-front in the first macro invocation, making it easier to audit and refactor in the future.

This refactor also has some functional changes. Only one is a true behavior change, however:
- The visible one is that SIMD shifts are now wrapping, not panicking on overflow
- `core::simd` now has a lot more instances of `#[must_use]`, which merely lints
- div/rem now perform a SIMD check but remain as before, which should improve performance but be invisible

Merge portable-simd#195 - portable-simd:trait-ops
Generic `core::ops` for `Simd<T, _>`

In order to maintain type soundness, we need to be sure we only implement an operation for `Simd<T, _> where T: SimdElement`... and also valid for that operation in general. While we could do this purely parametrically, it is more sound to implement the operators directly for the base scalar type arguments and then use type parameters to extend the operators to the "higher order" operations.

This implements that strategy and cleans up `simd::ops` into a few submodules:
- assign.rs: `core::ops::*Assign`
- deref.rs:  `core::ops` impls which "deref" borrowed versions of the arguments
- unary.rs: encloses the logic for unary operators on `Simd`, as unary ops are much simpler

This is possible since everything need not be nested in a single maze of macros anymore. The result simplifies the logic and allows reasoning about what operators are valid based on the expressed trait bounds, and also reduces the size of the trait implementation output in rustdoc, for a huge win of 4 MB off the size of `struct.Simd.html`! This addresses a common user complaint, as the original was over 5.5 MB and capable of crashing browsers!

This also carries a fix for a type-inference-related breakage, by removing the autosplatting (vector + scalar binop) impls, as unfortunately the presence of autosplatting was capable of busting type inference. We will likely need to see results from a Crater run before we can understand how to re-land autosplatting.

6094f22ceb impl unary.rs for Simd<{i,u}{8,16,32,64,size}, _>
In order to assure type soundness, these "base" impls
need to go directly on Simd<T, _> for every scalar type argument.
A bit of cleanup of ops.rs is still warranted.

2acf204b09 Rename to portable-simd and remove other names
Clean up references to the repo's previous name.
Removes the authors field, which is non-obligatory since RFC 3052.
Better to omit than confound: let git log be our witness.

Add 32-bit SIMD types i/u16x2 and i/u8x4. (#145)
These types are useful for the "SIMD32" instructions available on ARMv6
(except M-class), ARMv7 (M-class with DSP), and ARMv8.

Merge pull request #139 from rust-lang/feat/gather
Add SimdArray trait and safe gather/scatter API (rust-lang/stdsimd#139)
This PR has four parts, without which it doesn't make a lot of sense:
-    The introduction of the SimdArray trait for abstraction over vectors.
-    The implementation of private vector-of-pointers types.
-    Using these to allow constructing vectors with SimdArray::gather_{or, or_default, select}.
-    Using these to allow writing vectors using SimdArray::scatter{,_select}.
