fast/js/function-constructor-this-value.html was added in http://trac.webkit.org/changeset/127323 but it seems to fail on Chromium ports. Per discussion on IRC this seems like a V8 issue. http://test-results.appspot.com/dashboards/flakiness_dashboard.html#showExpectations=true&tests=fast%2Fjs%2Ffunction-constructor-this-value.html
Skipping the test in http://trac.webkit.org/changeset/127329
Marked LayoutTest bugs, bugs with Chromium IDs, and some others as WontFix. Test failure bugs still are trackable via TestExpectations or disabled unit tests.
