```
std: Add Wasm SIMD opcodes and value type

This adds the opcodes for both the simd128 and relaxed-simd features.
Those instructions are required by the self-hosted WebAssembly
backend. Additionally, this also adds the new `v128` Valtype which
is required to represent a 128bit simd value. SIMD values that do
not have exactly 128 bits will be represented differently.

```
