In generation of encoding functions for enumeration types,
the values used for generating the range check in case of a value range should be sorted and have duplicates removed. For per with optimization (per_rt2ct), sorting has been added. For both optimized and regular per, the sorting and duplicate removal code has been simplified. In case of value range, 'MIN' and 'MAX' is now also checked. The sorting of constraint values in the check phase remains.
