Improve sanity checking of interdiff test opcodes, and fix a test.
Review Request #8831 — Created March 20, 2017 and submitted
This improves our interdiff opcode sanity-checking, making sure that ranges are of the correct lengths. That also unveiled a problem with one of our tests that had a bad length. That unit test has been fixed accordingly.
Tested each of the failure paths.
Unit tests pass.
