Proof step 21 from proof okbytearray-put-byteval-equiv (previous step)

st[r -- _length] = intval(i0), st[r -- _type] = typeval(mkarraytype(byte_type)), j < i0, r -- _type ∈ st, r -- _length ∈ st, is_arrayref(r, i0, st[r -- i ', byteval(by)]), r ∈ st, 0 ≤ i0, 0 ≤ j, 0 < i0, is_bytevalue(st[r -- i ', byteval(by)][r -- j ']), i < 0 ∨ i0 ≤ i ∨ 0 ≤ i ∧ i < i0 ∧ r -- i ' ∈ st ∧ is_bytevalue(st[r -- i ']) ⊦ r -- j ' = r -- i ', r = jvmref, is_bytevalue(st[r -- j '])
