Implement multi-level page tables.
Define L1_MAP_ADDR_SPACE_BITS to be either the virtual address size
(in user mode) or physical address size (in system mode), and use
that to size l1_map. This rewrites page_find_alloc, page_flush_tb,
and walk_memory_regions.
Use TARGET_PHYS_ADDR_SPACE_BITS for the physical memory map based
off of l1_phys_map. This rewrites page_phys_find_alloc and
phys_page_for_each.
