9eb4237dfe fix #6292 
this patches a case where macro-finder is used with arrays. It doesn't work so macro quantifiers have to be re-instated to ensure correctness

floating points may also track bit-literals.
Since the legacy solver doesn't handle dual tracking of literals we just let the floating point solver track.

17fc438476 don't have bv-ackerman influence simplification 
previous scheme has Ackmerman module instrument main solver to backjump and simplify when reaching a threshold.
This destroys overall performance: simplification does many more things than invoking Ackerman axioms.
Having a dependency between simplification (in-processing) and depleting a priority queue of auxiliary axioms therefore hurts overall performance. It has to be decoupled. The current approach is now to empty the axiom queue on occasion.
It is still not ideal - it should be coupled with the search level - axioms don't survive higher levels where redundant clauses get garbage collected as they don't have a chance of being used.

48b13291d1 add bv-size reduce #6137 
- add option smt.bv.reduce_size.
  - it allows to apply incremental pre-processing of bit-vectors by identifying ranges that are known to be constant.
    This rewrite is beneficial, for instance, when bit-vectors are constrained to have many high-level bits set to 0.

1d87592b13 fixes to mod/div elimination 
elimination of mod/div should be applied to all occurrences of x under mod/div at the same time. It affects performance and termination to perform elimination on each occurrence since substituting in two new variables for eliminated x doubles the number of variables under other occurrences.

Also generalize inequality resolution to use div.

The new features are still disabled.
