Until now, the cross-over mutator would choke on several expressions
from DB and bail out (just wastes some time). We also have a script,
test_db.js to test on how many expressions it is going to bail out.
With this change, we already omit adding such expressions to the
DB in the first place. As a result, the test_db script now returns
zero failing expressions (while all other expressions remain).
Regression tests that now no longer apply are removed, instead a
test is added that ensures that a failing expression isn't added
to the DB.
