Avoid visiting dead large objects in RegionSpace::Walk

The motivation is to prevent large objects from being visited by
RegionSpace::Walk if it is called before the next GC's SetFromSpace
marks the large object as from-space. This fixes possible dangling
pointer issues.

A follow up CL will clear the empty unevac regions.
