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).

d5c6abe14d #close 5363 
Force in-lining auxiliary functions so that model values can be used by SPACER to retrieve counter-examples. This fixes the issue of terminating without a trace. It does not address inefficiency involved with invoking satisfiability checks to retrieve models during trace construction.
