Portable Packed SIMD Vectors for Rust standard library
They used to work (https://travis-ci.org/gnzlbg/packed_simd/builds/405449457) but now they fail; need to investigate more.
Example: `From for i64x2`: ```rust let v: i64x2 = 42_i32.into(); assert_eq!(v, i64x2::splat(42)); ``` Note: `impl From for Simd` is just `Simd::::splat(T)`.

This test passes on `s390x-unknown-linux-gnu` and `sparc64-unknown-linux-gnu` (it does not panic): ```rust #[test] pub fn scalar_test() { let z = 0_i128; let o = 1_i128; if o >> z !=...

The `arm-linux-androideabi` and `aarch64-linux-android` targets fail to compile `packed_simd` with its tests with the following error messages. `signal: 9, SIGKILL: kill` is probably the OOM killer in action. # arm-linux-androideabi...

We should test truncation, extensions, with different and the same vector.
Passing an index that is out-of-bounds to `shuffle!(a, b, [ids...])` produces a monomorphization-time error.
