Move TARGET_PHYS_ADDR_SPACE_BITS to target-*/cpu.h.
Removes a set of ifdefs from exec.c. Introduce TARGET_VIRT_ADDR_SPACE_BITS for all targets other than Alpha. This will be used for page_find_alloc, which is supposed to be using virtual addresses in the first place. Signed-off-by: Richard Henderson <rth@twiddle.net>
