        HTML5 parser should be within 1% of old parser performance

        Fix cast in this operator= to allow for assignment between vectors with
        different inline capacities (as clearly intended by its author).

        Stop using adopt().  I think this function is cause us to do extra
        mallocs that are hurting performance.  Instead of caching AtomicString
        on HTML5Token, just use the AtomicString on the old token.  Also,
        reserve inline capacity for 10 attributes.
