      Description

      The SATB enqueue function calls enqueue_known_active when SATB is active, and otherwise does nothing. There are places that are calling enqueue even though they've already verified SATB is active. These could instead be calling enqueue_known_active directly. G1 array copying is one such place. There may be others.
