Proof step 30 from proof ac-out (previous step)

∀ class1, st, val. class1 = `java.lang.Object' .class ∨ addclass(class1, fis0, st[_out, val]) = (addclass(class1, fis0, st)[_out, val]) ⊦ class1 = `java.lang.Object' .class, addclass(class1, fv + fis0, st[_out, val]) = (addclass(class1, fv + fis0, st)[_out, val])
