    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.
