Revoke rosalloc thread-local buffers at the checkpoint.
In the mark sweep collector, rosalloc thread-local buffers were
revoked during the pause. Now, they are revoked at the thread
checkpoint, as opposed to during the pause, which appears to help
reduce the pause time.
In Ritz MemAllocTest, the average sticky pause time went down ~20%
(925 us -> 724 us).
