Fix zygote live/mark bitmap size.
Fixed some errors with the sizes of mark/live bitmaps after zygote space creation.
This was causing us to occasionally have overlapping mark/live bitmaps.
Added a new verify objects mode called VERIFY_OBJECT_FAST which only checks objects and not their classes.
Refactored/optimized some of the scanning code to use xor to clear bits instead of and+not.
