Proof step 15 from proof isarray-notin-01 (previous step)

st[r -- _type] .type = mkarraytype(ty), r ∈ st, 0 < st[r -- _length] .intval, 0 ≤ i, i < st[r -- _length] .intval, okarray(r, ty, st), is_typevalue(st[r -- _type]), r -- _type ∈ st ⊦ r = jvmref, r -- i ' ∈ st

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals
