Nikolaj Bjorner 3433b14dfa 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.

- avoid more platform specific behavior when using m_mk_extract,
- rename mk_eq in bool_rewriter to mk_eq_plain to distinguish it from mk_eq_rw
- rework bv_lookahead to be more closely based on sls_engine, which has much better heuristic behavior than attempt 1.

Nikolaj Bjorner 87f7a20e14 Add (updated and general) solve_for functionality for arithmetic, add congruence_explain to API to retrieve explanation for why two terms are congruent Tweak handling of smt.qi.max_instantations 
Add API solve_for(vars).
It takes a list of variables and returns a triangular solved form for the variables.
Currently for arithmetic. The solved form is a list with elements of the form (var, term, guard).
Variables solved in the tail of the list do not occur before in the list.
For example it can return a solution [(x, z, True), (y, x + z, True)] because first x was solved to be z,
then y was solved to be x + z which is the same as 2z.

Add congruent_explain that retuns an explanation for congruent terms.
Terms congruent in the final state after calling SimpleSolver().check() can be queried for
an explanation, i.e., a list of literals that collectively entail the equality under congruence closure.
The literals are asserted in the final state of search.

Adjust smt_context cancellation for the smt.qi.max_instantiations parameter.
It gets checked when qi-queue elements are consumed.
Prior it was checked on insertion time, which didn't allow for processing as many
instantations as there were in the queue. Moreover, it would not cancel the solver.
So it would keep adding instantations to the queue when it was full / depleted the
configuration limit.

Nikolaj Bjorner 71bad7159b #7418 - circumvent use of timer threads to make WASM integration of z3 easier 
The scoped_timer uses a std::therad. Spawning this thread fails in cases of WASM.
Instead of adapting builds and using async features at the level of WASM and the client, we expose a specialized version of z3 that doesn't use threads at all, neither for solvers nor for timers.
The tradeoff is that the periodic poll that checks for timeout directly queries the global clock each time.
We characterize it as based on polling.

Nikolaj Bjorner 8a95dd4d65 A slice solver option for interactive use case 
A slice solver prunes the set of active assertions based on symbol occurrences in a goal that is tracked as a @query.
Ground assertions that have symbols intersecting with the query are included in the solver state, and quantifiers that with patterns that intersect with the slice are included. The slice is the fixedpoint of including symbols from all included assertions.
Enable the functionality for command-line use by setting solver.slice=true
