      The failure dict looks something like the following.
      It maps operator name (qualname) to a list of autogenerated tests.
      Each autogenerated test may have a check for the operator (if the operator is
      called by the test); the dictionary specifies if we should skip the check,
      or if we expect some check to fail.
