Test IndexedDB behavior when iterating backwards with and without NO_DUPLICATE

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".

dbname = "cursor-prev-no-duplicate.html"
indexedDB.deleteDatabase(dbname)
indexedDB.open(dbname)
store = db.createObjectStore('store')
store.createIndex('index', 'sorted')


populating store...
