Proof step 35 from proof sharing-twopaths (previous step)

refs = r0 + refs0, r0 = st[r -- sks] .refval, refs .last = st[r -- sks0] .refval, fits(r, sks0, st), fits(r, sks, st), validrefs(str, refs, mkclasstype(`java.lang.Object' .class), st) ⊦ sks = [], sks0 = [], r0 = jvmref, refs .last = jvmref, r = jvmref, sks = sks0, refs = [], sks ⊑ sks0, hasSharing(r, st)
