63c41c3e04 Use struct fixed_bits_info instead of separate arguments 
and track sat::literal as justifications rather than viable::entry
(we won't have a viable::entry for fixed bits coming from slicing)

Jakob Rath
e832325a8b viable::entry::refined can be a boolean flag 
because we always copy the 'src' from the original entry to the refined one
