Nikolaj Bjorner d9f9cceea4 use intervals for tracking bounds on arithmetic variables 
leverage interval propagation for bounds.
merge functionality with propagate-ineqs tactic
remove the new propagate-bounds tactic and instead use propagate-ineqs

Nikolaj Bjorner 7368f9f7d3 increase build version, better propagation in euf-egraph, handle assumptions in sat.smt 
- increase build version to 4.12.1. This prepares updated release for MacOs-11 build on x86
- move literal propagation mode in euf-egraph to a callback and traversal of equivalence class. Track antecedent by newest equality instead of root. This makes equality propagation to literals have similar behavior as in legacy solver and appears to result in a speedup (10% fewer conflicts on QF_UF/QG-classification/qg5/iso_icl478.smt2 in preliminary testing)
- fix interaction of pre-processing and assumptions. Pre-processing has to freeze assumption literals so they don't get eliminated. This is similar to dependencies that are already frozen.
