Description
The member _orig_end of the HeapRegion class stores the "original end" of the region that is needed to recover after making the region humongous.
The actual value of _orig_end is always _bottom + HeapRegion::GrainWords. There is no need to waste (up to) 8 bytes of storage for this trivial constant.
Remove the _orig_end member, and replace the getter with above calculation.
