Proof step 8 from proof okbar-norefval (previous step)

st[r -- _length] = intval(i0), st[r -- i '] = refval(r1), st[r -- _type] = typeval(mkarraytype(byte_type)), r -- _length ∈ st, ∀ j. 0 ≤ j ∧ j < i0 → r -- j ' ∈ st, 0 ≤ i, i < i0, r -- _type ∈ st, r ∈ st, 0 < i0, 0 ≤ i0, ∀ j. ¬ j < 0 ∧ ¬ i0 ≤ j → is_bytevalue(st[r -- j ']) ⊦ r = jvmref
