  Multiplies a 64-bit unsigned integer by a 32-bit unsigned integer and
  generates a 64-bit unsigned result.

  This function multiplies the 64-bit unsigned value Multiplicand by the 32-bit
  unsigned value Multiplier and generates a 64-bit unsigned result. This 64-
  bit unsigned result is returned.

  @param  Multiplicand  A 64-bit unsigned value.
  @param  Multiplier    A 32-bit unsigned value.

  @return Multiplicand * Multiplier.
