cpu-o3: Fix signed overflow in PhysRegIndex
PhysRegIndex is typed as signed short int.
Large number of registers make the index overflow and raises
physreg's out-of-range asssertion at Scoreboard::unset/setReg().
By changing the type to unsinged short int which RegIndex already
uses, we can mitigate the overflow issue without additional costs.
