  1. BUG, SIMD: Fix 64-bit integer divison by a scalar on MSVC <= 2017 

      The multiplier factor that used for integer division wasn't correctly
  calculated due inaccurate implementation of the emulated version
  of intrinsic `_udiv128`.

  2. BUG, SIMD: Fix unsigned 8-bit integer divison by a scalar 

      Same as 64-bit divistion, except quad wide divison leads
  to inaccurate multiplier in certain cases when the log2 of
  the divisor overflow to zero.
