Multiples a 64-bit unsigned integer by a 64-bit unsigned integer and
generates a 64-bit unsigned result.
This function multiples the 64-bit unsigned value Multiplicand by the 64-bit
unsigned value Multiplier and generates a 64-bit unsigned result. This 64-
bit unsigned result is returned.
If the result overflows, then ASSERT().
@param Multiplicand A 64-bit unsigned value.
