x86-64: Display eiz for address with the addr32 prefix

In 64-bit mode, display eiz for address with the addr32 prefix and without
base nor index registers.  For

	mov -0xccddef(,%eiz,), %rax

disassembler now displays:

	67 48 8b 04 25 11 22 33 ff 	mov -0xccddef(,%eiz,1),%rax

instead of

	67 48 8b 04 25 11 22 33 ff 	addr32 mov 0xffffffffff332211,%rax
