Proof step 24 from proof sharing-twopaths (previous step)

And obtained the following new goals

Proof step 11:
⊦ (r ' + refs)[# refs] = (r ' + refs) .last
Proof step 23:
st[r -- sks0] = refval(refs0 .last), st[r -- sks] = refval(r0), # sks1 = # refs0, st[r0 -- sks1] .refval = (r0 ' + refs0) .last, fits(r, sks0, st), fits(r, sks, st), validrefs(str, r0 ' + refs0, mkclasstype(`java.lang.Object' .class), st), fits(r0, sks1, st) ⊦ refs0 = [], r = jvmref, sks = sks0, sks = [], sks0 = [], r0 = jvmref, refs0 .last = jvmref, sks ⊑ sks0, hasSharing(r, st)
