/**

Rotates a 64-bit integer right between 0 and 63 bits, filling the high bits
|

with the high low bits that were rotated.

This function rotates the 64-bit value Operand to the right by Count bits.
|

|
|
The high Count bits are fill with the low Count bits of Operand. The rotated
|

|
|
value is returned.

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