Austin Clements d70b0fe6c4 runtime: fix preemption of root marking jobs ... The current logic in gcDrain conflates non-blocking with preemptible draining for root jobs. As a result, if you do a non-blocking (but *not* preemptible) drain, like dedicated workers do, the root job drain will stop if preempted and fall through to heap marking jobs, which won't stop until it fails to get a heap marking job. This commit fixes the condition on root marking jobs so they only stop when preempted if the drain is preemptible. Coincidentally, this also fixes a nil pointer dereference if we call gcDrain with gcDrainNoBlock and without a user G, since it tries to get the preempt flag from the nil user G. This combination never happens right now, but will in the future.
