Xeon E3-1241 v3 not correctly identified on hypervisor

[m-j-w]

Per the log of pkglisting, the cache sizes are wrong. Should be 8MB L3, and L2 looks suspicious. It should also have AVX2. First Haswell Xeon tested on thus far. Also possible that its a hypervisor problem. Check after next tag: remember to add full dump of cpuid registers to tests, plus a dump of /proc/cpuinfo on linux.
