Adds support for PSL
nondetbuilt-in.Supports both:
booleanargument as well asvalue_setargument with individual entries and ranges.Enforces type of each entry within value set is the same.
Computes total length of all ranges (e.g. for
{1,2,7 to 10,12}it is 6) and chooses uniformly a random numberwithin such range. The generated code then walks the
value_setand figures out which entry is the one chosen.Based on the chosen entry, correct value is returned.
TODO: Standard says the types of arguments can be arbitrary, as long as the context where
nondetcan accept such type.Currently, it only works for integers. I think it would be good to do it for enums too. More complex types IMHO do not make much sense.
