IndexedDB: Memory leak when deleting object stores with indexes
https://bugs.webkit.org/show_bug.cgi?id=98292
Reviewed by Tony Chang.
Reference cycles between IDBObjectStore and IDBIndex instances are explicitly
broken when the transaction completes (and the spec allows traversal to fail).
Deleted stores need to have the reference cycle broken too.
Caught by running valgrind over: storage/indexeddb/keypath-basics.html
* Modules/indexeddb/IDBTransaction.cpp:
(WebCore::IDBTransaction::objectStoreDeleted): Add store to set.
(WebCore::IDBTransaction::dispatchEvent): Notify stores in set.
* Modules/indexeddb/IDBTransaction.h: Add set of deleted stores.
