      [js-fuzzer] Make db more robust to failing code fragments. · 0ffc1ba5
      Michael Achenbach authored
      Until now, the cross-over mutator would choke on several expressions
      from DB and bail out (just wastes some time). We also have a script,
      test_db.js to test on how many expressions it is going to bail out.
      
      With this change, we already omit adding such expressions to the
      DB in the first place. As a result, the test_db script now returns
      zero failing expressions (while all other expressions remain).
      
      Regression tests that now no longer apply are removed, instead a
      test is added that ensures that a failing expression isn't added
      to the DB.

      This is a JavaScript fuzzer originally authored by Oliver Chang. It
      is a mutation based fuzzer using Babel code transformations. For more
      information see the included README.md.
      
      The original code was altered:
      - Add new V8 copyright headers.
      - Make the test expectation generator aware of the headers.
      - Fix file endings for presubmit checks.
      - Fix `npm test` on fresh checkout with a new fake DB.
      - Make test skipping work with new v8/tools location.
      - OWNERS file.
      - New title section in README.md.
