Shifts a 64-bit integer right between 0 and 63 bits. The high bits are filled

with the 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.

If Count is greater than 63, then ASSERT().
