6297c001ee remove legacy solve_eqs_tactic entirely 
also, bug fixes to elim_unconstrained (elim_uncnstr2) which is to replace legacy tactic for eliminating unconstrained constants.

c24d445886 fix #6355 
conversion from AIG to expressions should always use the optimized conversion function.

the aig-tactic should throttle regarding output bloat from AIG.
If the expression after AIG simpification, for whatever reason, is bloated the rewrite does not take place.
