[heap] Move to page lookups for SemiSpace, NewSpace, and Heap containment methods Preparing the young generation for (real) non-contiguous backing memory, this change removes object masks that are used to compute containment in semi and new space. The masks are replaced by lookups for object tags and page headers, where possible. Details: - Use the fast checks (page header lookups) for containment in regular code. - Use the slow version that masks out the page start adress and iterates all pages of a space for debugging/verification. - The slow version works for off-heap/unmapped memory. - Encapsulate all checks for the old->new barrier in Heap::RecordWrite().
