Nikolaj Bjorner 304b316314 move bounded division lemmas to nla solver/ nla_divisions. 2023-01-30 11:11:04 -08:00
Nikolaj Bjorner 8e37e2f913 handle non-linear division axioms, consolidate backtracking state in nla_core
this update enables new incremental linear axioms based on division terms.
It also consolidates some of the backtracking state in nla_core / emons to use stack traces instead of custom backtracking state.

Nikolaj Bjorner 8ea49eed8e convert reduce-args to a simplifier
- convert reduce-args to a simplifier. Currently exposed as reduce-args2 tactic until the old tactic code gets removed.
- bug fixes in model_reconstruction trail
  - allow multiple defs to be added with same pool of removed formulas
  - fix tracking of function symbols instead of expressions to filter replay
- add nla_divisions to track (cheap) divisibility lemmas.
