IMPORTANT NOTE: This will likely be macroized to reduce boilerplate. Publishing now to start discussion about approach, which ops are needed, etc. Omitted functions are commented out in machine-operator.h so start there. Takes the SIMD runtime intrinsics as a starting point for defining TF machine operators. The rationale for omitting functions is: - UInt constructors. int and uint aren't distinguished in wasm. - Check functions. - 'FromXxxBits' functions. These are essentially casts. - Simple Load / Store functions. Existing load / store with SIMD type should work. - Uint functions, except where their behavior is bitwise different from the Int function.
