e4697fe18e remove set cardinality operators from array theory. Make final-check use priority levels 
Issue #7502 shows that running nlsat eagerly during final check can block quantifier instantiation.
To give space for quantifier instances we introduce two levels for final check such that nlsat is only applied in the second and final level.

809838fede solve for fold, expand rewrites under fold/map 
Occurrences of map and fold are interpreted.
They are defined when the seq argument is expanded into a finite
concatenation. The ensure this expansion takes place, each fold/map term
is registered and defined through rewrites when the seq argument simplifies.
