Detect unused steps in isolation specs and do some cleanup

This is useful for developers to find out if an isolation spec is
over-engineered or if it needs more work by warning at the end of a
test run if a step is not used, generating a failure with extra diffs.

While on it, clean up all the specs which include steps not used in any
permutations to simplify them.

This is a backpatch of 989d23b and 06fdc4e, as it is becoming useful to
make all the branches consistent for an upcoming patch that will improve
the output generated by isolationtester.
