Fix a bug in 31 bit arithmetic, leading to failing conversion tests.
On 64 bits architectures, integers could have some of their 32 msb set to 1
internally in the VM. When read back to a Coq term, this was not observable. But
an equality test would fail. From the user point of view, the symptom was that
vm_compute; reflexivity would succeed but the subsequent Qed would fail.
Bug reported by Tahina Ramananandro.
