Add a new CPU model called 'EPYC' to model processors from AMD EPYC
family (which includes EPYC 76xx,75xx,74xx, 73xx and 72xx).
The following features bits have been added/removed compare to Opteron_G5
Added: monitor, movbe, rdrand, mmxext, ffxsr, rdtscp, cr8legacy, osvw,
fsgsbase, bmi1, avx2, smep, bmi2, rdseed, adx, smap, clfshopt, sha
xsaveopt, xsavec, xgetbv1, arat
Removed: xop, fma4, tbm
The patch is depend on EPYC CPU model supported introduced in qemu [1]

We list model's features sorted by name. ACK with the issues fixed. However, it would be nice to add some CPUID data to our test suite. Luckily enough I have such data so I'll just resend [1] a fixed version of this patch with the test data added.

Thank you very much Jirka. Now I need to go and talk to our IT folks to see what is going on.
