Wasm32 SIMD implementation
This code is based on rust_sse2.rs of the same distribution, and is
subject to further improvements. Some comments are left intact even if
their applicability is questioned.
SIMD implementation is gated by `wasm32-simd` feature, portable version
is used otherwise.
Performance measurements with a primitive benchmark with ~16Kb of data:
| M1 native | 11,610 ns |
| M1 WASM SIMD | 13,355 ns |
| M1 WASM | 22,037 ns |
| x64 native | 6,713 ns |
| x64 WASM SIMD | 11,985 ns |
| x64 WASM | 25,978 ns |
wasmtime v12.0.1 was used on both platforms.
Closes #187.
