@wintersteiger
This example exposes a bug in is_unique_value
```
(assert (= (fp.to_real ((_ to_fp 8 24) (_ bv4286579200 32))) (fp.to_real ((_ to_fp 8 24) (_ bv4286578944 32)))))
(check-sat)
```
It returns true for fp representations that map to NaN. It can only return true for fp values that are unique relative to having no other bit-vector representation so not corresponding to an equivalence class of values such as NaN.
I am having it return false. If there is a way to refine the test it will catch some earlier inferences.

1f4a7c5101 logging: don't call the returned function twice (one for log, one for return) 
Z3_simplify() does RETURN_Z3(simplify(...)), hence the function was being called twice
it turns out simplify is not idempotent, so calling it twice can result in different results
thus breaking the log.

Pull request #5512 identifies a in line 1139 where the const-case-multiplier constructor returns false and does useless work.
In this update we also remove mk_const_multiplier because code path is subsumed by mk_const_case_multiplier.

09696e989e add missing lambda defs per #5509 
the result is now unknown because the nested expression contains exists, which doesn't get replaced by universal quantifier which is assumed by the legacy core.
The legacy core should not depend on universal quantifiers only, but fixing this is a risk. Workaround is to rewrite goals using forall only (replace exists by de-Morgan dual).

can't use auto-config if there are no assertions. Auto-config only works properly for one-shot mode since theories aren't loaded on demand in this solver.
