Proof step 4 from proof unchNorec-sym (previous step)

st0[r -- _type] .type = mkclasstype(class), st[r -- _type] = st0[r -- _type], fs ' ∈ instfields(class), is_classtype(st0[r -- _type] .type), ∀ fs. fs ' ∈ instfields(class) → st[r -- fs '] = st0[r -- fs '] ⊦ st0[r -- fs '] = st[r -- fs '], r = jvmref

And obtained the following new goals

Proof step 3:
st[r -- _type] = st0[r -- _type], st0[r -- _type] .type = mkclasstype(class), fs ' ∈ instfields(class), ∀ fs. fs ' ∈ instfields(class) → st[r -- fs '] = st0[r -- fs '] ⊦ r = jvmref, st0[r -- fs '] = st[r -- fs ']
