b6d0eec3de Wrap bitshifts in ops.rs 
For all other operators, we use wrapping logic where applicable.
This is another case it applies. Per rust-lang/rust#91237, we may
wish to specify this as the natural behavior of `simd_{shl,shr}`.

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.

257fa7aa6d Drop splats for Simd<T, _> 
Unfortunately, splatting impls currently break several crates.
Rust needs more time to review possible mitigations, so
drop the impls for the `impl Add<T> for Simd<T, _>` pattern, for now.

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.

b2dac7124b Uncomment AVX512 byte vector conversions

51ff925925 impl assign.rs<U> for Simd<T, _> 
Instead of implementing {Op}Assign traits for individual scalar type args
to Simd<_, _>, use parametric impls that reassert the bounds of the binary op.

0a6992f5bf impl deref.rs<&Self> for Simd<T, _> 
Instead of implementing each "deref" pattern for every single scalar,
we can use type parameters for Simd operating on &Self.
We can use a macro, but keep it cleaner and more explicit.

ab8eec7cba Fixup import pathing for core 
This changes simd_swizzle! to a decl_macro to give it a path,

6d23662689 Add {gather,scatter}_select_unchecked 
This unsafe variant allows the thinnest API, in case LLVM cannot
perform loop-invariant code motion on a hot loop when the safe
form is used.

An unchecked variant could be added to other forms, but doesn't
seem likely to improve anything, since it would just add heavier
codegen.

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}.

a2302da5b2 Move macros.rs to first.rs 
This awkwardly has to go first right now, and we don't want more
macros to go into this ambiguously named mod, so let's rename it
to be more literal.

39fb223385 Partially carve macros.rs into other files 
The base impl_vector! in macros.rs is staying put for the moment as
it must go first before everything in order to work.

Everything else, like transmutes, specific type impls, etc. have
been moved into appropriate files elsewhere to subdivide concerns.

2f2a463c0d Remove From<Scalar> for SimdTy impl 
0. It was not being tested.
1. The possible conversions are ambiguous between splatting
   and setting a single value but zero-initializing the rest.
2. Splat works fine.
