Rotates a 32-bit integer left between 0 and 31 bits, filling the low bits
with the high bits that were rotated.
This function rotates the 32-bit value Operand to the left by Count bits. The
low Count bits are fill with the high Count bits of Operand. The rotated
value is returned.
If Count is greater than 31, then ASSERT().
@param Operand The 32-bit operand to rotate left.
@param Count The number of bits to rotate left.
