@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.

Nuno Lopes 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.

Nikolaj Bjorner e3a83dd0dd Integrate fixes from #5512 
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.
