-Routine Description:
-  This routine allows a 64 bit value to be right shifted by 32 bits and returns the 
-  shifted value.
-  Count is valid up 63. (Only Bits 0-5 is valid for Count)
-Arguments:
-  Operand - Value to be shifted
-  Count   - Number of times to shift right.
- 
-Returns:
-
-  Value shifted right identified by the Count.
