Add phenom CPU descriptor (Alexander Graf)

As part of my ongoing effort to make nested SVM useful, I started working to get
VMware ESX run inside KVM.

VMware couples itself pretty tightly to the CPUID, so it's a good idea to emulate
a machine that officially supports SVM and should thus exploit the powers of
nested virtualization.

This patch adds a Phenom CPU identifier, that resembles a real-world phenom
CPU as closely as possible.
