-/**
- Shifts a 64-bit integer right between 0 and 63 bits. The high bits
- are filled with original integer's bit 63. The shifted value is returned.
-
- This function shifts the 64-bit value Operand to the right by Count bits. The
- high Count bits are set to bit 63 of Operand. The shifted value is returned.
-
- @param Operand The 64-bit operand to shift right.
- @param Count The number of bits to shift right.
-
- @return Operand arithmetically shifted right by Count.
