[libvirt] [PATCH 10/17] cpu: Add IvyBridge-IBRS CPU model

This is a variant of IvyBridge with indirect branch prediction protection. The only difference between IvyBridge and IvyBridge-IBRS is the added "spec-ctrl" feature. The IvyBridge-IBRS model in QEMU is a bit different since IvyBridge got several additional features since we added it in cpu_map.xml: arat, vme, xsaveopt Adding them only to the -IBRS variant would confuse our CPU detection code.
