This adds version number to CPU model names on the "pc-<version>" machine-types, so we can create new models with bug fixes while keeping compatibility when using older machine-types.

When naming the existing models, I used the last QEMU version where the model was changed (see summary below), but by coincidence every single one was changed on QEMU-1.1.

- Conroe, Penryn, Nehalem, Opteron_G1, Opteron_G2, Opteron_G3: added on 0.13, changed on 1.1 - Westmere, SandyBridge, Opteron_G4: added on 1.1

Hi Eduardo, What models would be listed by "qemu-system-x86_64 -cpu ?"? Only non-versioned model aliases or full names with versions or both? Jirka
