Fix region space when used with SetLengthToUsableSizeVisitor.
The region space relies on obj->SizeOf for some of its logic.
By having SetLengthToUsableSizeVisitor "change" the SizeOf
what's being allocated.
The bug happens during RegionSpace::ClearFromSpace: for unevac regions
we iterate over following regions. If LiveBytes != Top() - Begin()
(which happen for large allocations using SetLengthToUsableSizeVisitor),
we break the loop.
The next region to analyze is a large tail, and we see LiveBytes() == 0
(tails apparently always have live bytes == 0), the code is then
happy to release the large tail, even though the large object is still
live.
