Add the ability to customize incremental pre-processing simplification for the SMTLIB2 front-end. The main new capability is to use pre-processing tactics in incremental mode that were previously not available. The main new capabilities are - solve-eqs - reduce-args - elim-unconstrained There are several more. Documentation and exposed simplifiers are populated incrementally. The current set of supported simplifiers can be inspected by using z3 with the --simplifiers flag or referring to https://microsoft.github.io/z3guide/docs/strategies/simplifiers Some pending features are: - add the ability to update parameters to simplifiers similar to how tactics can be controlled using parameters. - expose simplification solvers over the binary API.
