        <rdar://problem/4308243> 8F36 Regression: crash in malloc_consolidate if you use a .PAC file

        The original fix missed the oversized cell case. Added a test for "currentThreadIsMainThread ||
        imp->m_destructorIsThreadSafe" where we collect oversized cells.

        We don't have a way to test PAC files yet, so there's no test attached.

        (KJS::Collector::collect): test the thread when we collect oversized cells
