Proof step 15 from proof okarray-put-badfield (previous step)

st[r -- _type] .type = mkarraytype(ty0), st[r -- _length] = intval(i), 0 ≤ i, r -- _length ∈ st, is_arrayref(r, i, st), r -- _type ∈ st, is_typevalue(st[r -- _type]), ty0 ≤ ty, r ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → okval(st[r -- j '], ty) ⊦ fs ' = _length, fs ' = _type, r = jvmref, okarray(r, ty, st[r -- fs ', val])
