  -----------
  [ConstantRangeTest] Print detailed information on failure (NFC)

When the optimality check fails, print the inputs, the computed
range and the better range that was found. This makes it much
simpler to identify the cause of the failure.

Make sure that full ranges (which, unlikely all the other cases,
have multiple ways to construct them that all result in the same
range) only print one message by handling them separately.
