Optimize RegionSpace::ClearFromSpace()
We perform madvise() and mprotect() syscalls in
RegionSpace::ClearFromSpace() for every region that we reclaim. This was
being done while holding region_lock_. This has the potential to stall
the TLAB allocation requests.
In this CL, we pull out system calls out of the critical section of
region_lock_.
