target-i386: fix 32-bit addresses in LEA
This was found with test-i386. The issue is that instructions
such as
addr32 lea (%eax), %rax
did not perform a 32-bit extension, because the LEA translation
skipped the gen_lea_v_seg step. That step does not just add
segments, it also takes care of extending from address size to
pointer size.
