Currently, if the gcWork runs out of work, we'll fall out of the GC worker, even though flushing the write barrier buffer could produce more work. While this is not a correctness issue, it can lead to premature mark 2 or mark termination. Fix this by flushing the write barrier buffer if the local gcWork runs out of work and then checking the local gcWork again. This reduces the number of premature mark terminations during all.bash by about a factor of 10. Updates #26903. This is preparation for eliminating mark 2.
