Fix case where RE unfolding generates a trivially true lemma (#6267)
An RE unfolding lemma may rewrite to true for tautological RE memberships that our rewriter does not rewrite the membership to true.
An example is (str.in_re x (re.* (re.union (str.to_re "A") (str.to_re x))).
This PR ensures we are robust to these cases.
This fixes benchmarks 3-5 from #6203. Benchmark 3 is added here, 4-5 time out.
