      [WASM SIMD] Implement primitive shuffles. · 5806d862
      bbudge authored
      - Adds unary Reverse shuffles (swizzles): S32x2Reverse, S16x4Reverse,
        S16x2Reverse, S8x8Reverse, S8x4Reverse, S8x2Reverse. Reversals are
        done within the sub-vectors that prefix the opcode name, e.g. S8x2
        reverses the 8 consecutive pairs in an S8x16 vector.
      
      - Adds binary Zip (interleave) left and right half-shuffles to return a
        single vector: S32x4ZipLeft, S32x4ZipRightS16x8ZipLeft, S16x8ZipRight,
        S8x16ZipLeft, S8x16ZipRight.
      
      - Adds binary Unzip (de-interleave) left and right half shuffles to return
        a single vector: S32x4UnzipLeft, S32x4UnzipRight, S16x8UnzipLeft,
        S16x8UnzipRight, S8x16UnzipLeft, S8x16UnzipRight.
      
      - Adds binary Transpose left and right half shuffles to return
        a single vector: S32x4TransposeLeft, S32x4TransposeRight,
        S16x8TransposeLeft, S16xTransposeRight, S8x16TransposeLeft,
        S8x16TransposeRight.
      
      - Adds binary Concat (concatenate) byte shuffle: S8x16Concat #bytes to
        paste two vectors together.
