    imgproc:simd Enable VSX and wide universal intrinsics for accumulate operations · 8965f3ae
    Sayed Adel authored
      - improve cpu dispatching calls to allow more SIMD extentions
        (SSE4.1, AVX2, VSX)
      - wide universal intrinsics
      - replace dummy v_expand with v_expand_low
      - replace v_expand + v_mul_wrap with v_mul_expand for product accumulate operations
      - use FMA for accumulate operations
      - add mask and more types to accumulate's performance tests
