Properly distinguish which EQC to assign values in datatypes, use assertRepresentative. Disable regression related to records. Enable fmf-fun related regression (modified). Apply modified version of Morgan's patch to fix tuples/records in model. Fix bug with sort inference + patterns. Minor infrastructure.
