removing dependencies on simplifier, support SMTLIB2 parametric algebraic datatypes.
This is a breaking change. It introduces two substantial changes:
1. The legacy simplifier is removed. It was obsoleted with the introduction of the rewriter facilities, but many dependencies made it a major change to remove the legacy simplifier. All uses of the legacy simplifier have now been replaced by corresponding calls to the rewriter. It means that some normalization may behave differently. At this point, Z3 passes regressions and passes performance tests without regressing.
2. Algebraic datatypes in the form of SMT-LIB2.6 are now supported. These generalize the datatypes supported so far as parametric datatype constructors may be applied to different arguments within a recursive definition.
