Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 237:
st[r0 -- sks] = refval(r) ∧ is_referencevalue(st[r0 -- sks]), r = r0, (st[r0 -- i ', refval(r4)][r4 -- sks3]) = refval(r1), st[r0 -- _type] .type = mkarraytype(ty), (st[r0 -- i ', refval(r4)][r0 -- (sks + i ' ' + sks1)]) = refval(r1), fits(r4, sks3, st[r0 -- i ', refval(r4)]), disjoint(str, r0 ' + r4 ', st), validref(str, r4, ty, st), fits(r0, sks + i ' ' + sks1, st[r0 -- i ', refval(r4)]), i < st[r0 -- _length] .intval, 0 ≤ i, 0 < st[r0 -- _length] .intval ⊦ r4 = jvmref, sks3 = [], sks + i ' ' + sks1 = i ' ' + sks3, r0 = jvmref, r0 = r4, r1 = jvmref, junkref(str, r0, st), hasSharing(r4, st), hasSharing(r0, st), ∃ sks2. ¬ (sks2 + i ' ' ⊑ sks → st[r0 -- sks2] .refval ≠ r0)
