    [simulator] Make reference redirection thread-safe. · 34e79456
    neis authored
    In the simulators, the ExternalReference constructor rewrites external
    addresses, which involves mutating a linked list rooted in the isolate.
    
    We already construct external references concurrently (at least in Turbofan),
    but the list mutation was not thread-safe (though no crashes are known). This
    CL adds the necessary locking.
