           Summary: Add MessageQueue::removeWithPredicate to remove
                    certain tasks without pulling them from the queue.
           Product: WebKit
           Version: 528+ (Nightly build)

As part of removing thread-safe refcounting from tasks, it makes sense to add
the method on MessageQueue that would remove specified set of tasksk from the
queue. Otherwise, this operation is done by removing tasksk from the queue and
then re-inserting them back, which is longer, results in more locking
operations and doesn't help bug 30612.
