Our structured cloning implementation does not encode all of RegExp's flags

Our structured cloning implementation does not encode all of RegExp's flags.

This is causing WebKit to fail one of the subtests on http://wpt.live/IndexedDB/structured-clone.any.html?61-80. This subtest is passing in both Chrome and Firefox.

Need to add `hasIndices` flag ("d") too (this is new flag introduced super recently).
Also, can you add a test for "d" flag case?
