nickysn c9f8703679 + set ref.segment to NR_SS for all temps/localvars on i8086. This allows the
segment to survive e.g. several nested vecnodes, which cause the base register
  to change from BP to something else. In the cases where the ss: prefix is not
  needed, it is removed by make_simple_ref.
+ remove the ss: prefix in the several cases where make_simple_ref isn't called
  (namely spilling and tcg8086.a_call_reg_far)
