Intel CPUs store the number of cores in CPUID leaf 4. So push

There's a slight compatibility risk here. If a guest has broken
handling for cpuid level 4, then upgrading qemu would cause it to behave
I don't think that's an issue for this patch, just highlighting the need
for a systematic treatment of backward compatibility.
