separate fixed from bits to allow updates that break tabu
...
- range and fixed restrictions on terms are based on constraints and can be violated temporarily.
- bv_eval currently does not allow updating over fixed bits which leads to non-termination. TODO
- lookahead only considers tabu when setting values of variables.
