We're currently maintaining two outputs for cube regression test. But that appears to be unsuitable, because these outputs are different in out few checks involving scientific notation. So, split checks involving scientific notation into separate test, making contrib/cube easier to maintain. Backpatch to all supported versions in order to make further backpatching easier.
