-Routine Description:
- 
-  This routine allows a 64 bit value to be left 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 left.
-  
-Returns:
-
-  Value shifted left identified by the Count.
