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#274 : Use SIMD equality for PartialEq on SIMD vectors

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#272 : Standardize documentation for SIMD vector and mask types
...
This is a documentation-only patch that standardizes the presentation of vector types like `u32x4` and mask types like `mask32x16`.
The reasoning behind the patch was as follows:
1. Standardized terminology should be preferred, so `element` instead of `value` and `SIMD vector` instead of `vector`. These terms appear in the rest of the documentation and tutorials.
2. Try to avoid situations where two numbers are next to each other. So `16 elements of 32 bits` instead of `16 32-bit elements`.
4. Try to anticipate what readers are looking for -- so state the full bit-width directly.
### Vector Types
- Before: Vector of 32 `i8` values
- After: A 256-bit SIMD vector with 32 elements of type `i8`.
### Mask Types
- Before: Vector of 16 16-bit masks
- After: A mask for SIMD vectors with 16 elements of 32 bits.
