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.
