For all targets, into this new file move TARGET_LONG_BITS, TARGET_PAGE_BITS, TARGET_PHYS_ADDR_SPACE_BITS, TARGET_VIRT_ADDR_SPACE_BITS, and NB_MMU_MODES. Include this new file from exec/cpu-defs.h. This now removes the somewhat odd requirement that target/arch/cpu.h defines TARGET_LONG_BITS before including exec/cpu-defs.h, so push the bulk of the includes within target/arch/cpu.h to the top.
