This CL implements MemoryAllocator::LookupChunkContainingAddress, which
will be used for conservative stack scanning. The method determines
whether an address that may be an inner pointer is contained in some
allocated (normal or large) page. To achieve this, the CL introduces a
page database in the memory allocator.
