- Rotates a 64-bit integer left between 0 and 63 bits, filling
- the low bits with the high bits that were rotated.
-
- This function rotates the 64-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.
-
- @param Operand The 64-bit operand to rotate left.
- @param Count The number of bits to rotate left.
-
- @return Operand <<< Count
