Proof step 11 from proof fits-no-refval (previous step)

st[r -- _type] .type = mkclasstype(class), st[r -- sk0] = refval(r0), is_obj(str, r, st), junkref(str, r0, st), sks1 ⊑ sks, fits(r0, sks + sk ', st), is_classtype(st[r -- _type] .type), sk0 ∈ instfields(class), ∀ sks0, r, sk, st, str. sks0 ⊑ sks ∧ fits(r, sks + sk ', st) → is_referencevalue(st[r -- sks0]) ∨ junkref(str, r, st) ⊦ r = jvmref, junkref(str, r, st), is_referencevalue(st[r -- (sk0 ' + sks1)])

Proof step 10:
st[r -- sk0] = refval(r0), st[r -- _type] .type = mkclasstype(class), sk0 ∈ instfields(class), fits(r0, sks + sk ', st), sks1 ⊑ sks, junkref(str, r0, st), is_obj(str, r, st), ∀ sks0, r, sk, st, str. sks0 ⊑ sks ∧ fits(r, sks + sk ', st) → is_referencevalue(st[r -- sks0]) ∨ junkref(str, r, st) ⊦ r = jvmref, is_referencevalue(st[r -- (sk0 ' + sks1)]), junkref(str, r, st)
