5974a2dc58 remove m_b from lar_core_solver 
the column vector is pure overhead for the way the lar solver uses lp.
Some other solver modules use column vectors b and integrate with the lp_core_solver_base. The interaction model should be reviewed.
Unused solvers should be removed to make it easier to maintain this code.

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.

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.
