Fixed bug: barriers cannot be active during sweep

Barriers cannot be active during sweep, even in generational mode.
(Although gen. mode is not incremental, it can hit a barrier when
deleting a thread and closing its upvalues.)  The colors of objects are
being changed during sweep and, therefore, cannot be trusted.
