Chipset.
So if the chipset only allows accesses that are 64-bit, then you'll
want to have hierarchical dispatch filter non 64-bit accesses and
raise an MCE appropriately.
So you don't need anything in MemoryRegion, you need code in the
dispatch path.
MemoryRegion *is* the dispatch path. Only done declaratively so we can
flatten it whenever it changes.
