WebAssembly SIMD

WebAssembly SIMD will expose hardware SIMD instructions to WebAssembly applications in a platform-independent way. Implementations will explore using SIMD.js as a basis for WebAssembly SIMD. Add three SIMD vector types: float32x4, float64x2, and int32x4, and corresponding Typed Array views. SIMD can speed up applications that process lots of data that is naturally organized as 2, 3, or 4 element vectors. SIMD is also useful when compiling native code to WebAssembly.
