Exceptions thrown in JSDictionary::get() are not cleared, causing subsequent calls to JSDictionary::get() to fail spuriously.

This change is necessary to implement IndexedDB for JSC. Without this change, numerous calls to Dictionary::get() and Dictionary::getWithUndefinedOrNullCheck() fail in IDBDatabase::createObjectStore() and IDBObjectStore::createIndex() because earlier accesses to the options dictionary generated exceptions. With this proposed patch and that in bug 103484, IndexedDB for JSC passes 143 out of 196 layout tests in storage/indexeddb.
Comment on attachment 177318 [details] Patch I think this problem should be fixed in the IndexedDB layer not in the Dictionary layer. Please see discussion in bug 96614.
