(*LENB: translation of sp. Contrary to selection phase,
  the use of eval_operation (and the existing lemmas about
  eval_operation_inject) here suggests we should
  require sp=Vptr b Int.zero and sp' = Vptr b' Int.zero instead
  of sp=Vptr b i and sp' = Vptr b' i for some arbitrary i.
  Let's see whether this works...*)
