Heuristic if-then-else split applied rule case distinction

And obtained the following new goals

Proof step 17:
rk ∈ st, is_shortvalue(st[rk]), ¬ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st ∨ st[jvmref -- mkfs(class, void_type, `initstate' .field) '] ≠ initval(undone), jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st ∨ ¬ _uninit ∈ st, ¬ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st ∨ st[jvmref -- mkfs(class, void_type, `initstate' .field) '] ≠ initval(error) ⊦ ¬ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st ∨ ((jvmref -- mkfs(class, void_type, `initstate' .field) ' = rk ⊃ shortval(sho); st[jvmref -- mkfs(class, void_type, `initstate' .field) '])) ≠ initval(error)
Proof step 20:
rk ∈ st, is_shortvalue(st[rk]), ¬ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st ∨ st[jvmref -- mkfs(class, void_type, `initstate' .field) '] ≠ initval(undone), jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st ∨ ¬ _uninit ∈ st, ¬ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st ∨ st[jvmref -- mkfs(class, void_type, `initstate' .field) '] ≠ initval(error) ⊦ ¬ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st ∨ ((jvmref -- mkfs(class, void_type, `initstate' .field) ' = rk ⊃ shortval(sho); st[jvmref -- mkfs(class, void_type, `initstate' .field) '])) ≠ initval(undone)
