Please review this small fix which mangles freed heap regions in G1. I 
took the opportunity to make mangle_unused_area() and 
mangle_unused_area_complete() pure virtual, and null-implemented them in 
compactibleFreeListSpace instead. I also removed 
Space::mangle_region(MemRegion mr) which was never called.
