It's become evident during the work on https://bugs.webkit.org/show_bug.cgi?id=31863 that it's difficult to upstream the existing autotests in tests/auto/qscript* as-is, because the test functions are long and have many dependencies (e.g. relying on other QtScript API that hasn't been upstreamed yet).
Once all the API has been upstreamed, we need to ensure that the upstreamed tests are a super-set of the "old" tests.
