Implement dynamic byte-swizzle prototype (rust-lang/portable-simd#334) 
This is meant to be an example that is used to test
a Rust intrinsic against, which will replace it.
The interface is fairly direct and doesn't address
more nuanced or interesting permutations one can do,
nevermind on types other than bytes.

The ultimate goal is for direct LLVM support for this.

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.
Indeed, their presence may provide confusing results during integration attempts.

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.
