Proof step 8 from proof addclass-update-sw (previous step)

fv = sk × val, ∀ r, class0, fis0, st. r = jvmref ∨ update(r, fis1, addclass(class0, fis0, st)) = addclass(class0, fis0, update(r, fis1, st)) ⊦ r = jvmref, (update(r, fis1, addclass(class0, fis0, st))[r -- sk, val]) = addclass(class0, fis0, update(r, fv ' + fis1, st))

Proof step 7:
∀ r, class0, fis0, st. r = jvmref ∨ update(r, fis1, addclass(class0, fis0, st)) = addclass(class0, fis0, update(r, fis1, st)) ⊦ r = jvmref, (update(r, fis1, addclass(class0, fis0, st))[r -- sk, val]) = addclass(class0, fis0, update(r, (sk × val) ' + fis1, st))
