Change card cache mod-union table to use bitmaps
Previously used card sets, using bitmaps saves memory and slightly
increases performance.
Added mod union table test.
Performance EvaluateAndApplyChanges (minimal changes):
Before (card cache image mu table):
UpdateAndMarkImageModUnionTable: Avg: 524.320us
ImageModUnionClearCards: Avg: 54.580us
Native PSS: ~67500kB
After (card cache image mu table):
UpdateAndMarkImageModUnionTable: Avg: 515.600us
ImageModUnionClearCards: Avg: 53.780us
Native PSS: ~66014kB
Native PSS was higher before since the mod_union_table->SetCards()
which happens pre zygote fork was allocating a large amount of
std::nodes.
