Description
Current G1CollectionSetChooser contains both the collection set candidates (i.e. the set of old gen candidate regions) and the algorithm (and various helper class members) to select these regions from the set of HeapRegions. That makes the G1CollectionSetChooser quite a bit hard to read. Ideally something like G1CollectionSetCandidates candidates = G1CollectionSetChooser::select_candidates(...); would be much easier to read. Also remove the really hacky use of GrowableArray.
