Fix "finish" with range types on ARM

On ARM (I tested big-endian but it may not matter), "finish" can
sometimes print the wrong result when the return type is a range type.
Range types should really be treated as their underlying type
(normally integer, but sometimes fixed-point).  This patch implements
this.
