0d56edb65c Fix missing boolean propagation after boolean conflict 
Usually in SAT solving, the conflict clause has at least two false literals at the max level (otherwise, the last literal would have been propagated at an earlier level).
But here we are adding clauses on demand; so after backtracking we may have the case that the conflict clause has exactly one undefined literal that must be propagated explicitly.

917e1b6a4c When adding clauses, prioritize bool-propagation over evaluation 
See test_band1 and clause:  v2 == v0 & v1  -->  v2 <= 0
