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