Jakob Stoklund Olesen 6b359ecd43 Enable SandyBridgeModel for all modern Intel P6 descendants.
All Intel CPUs since Yonah look a lot alike, at least at the granularity
of the scheduling models. We can add more accurate models for
processors that aren't Sandy Bridge if required. Haswell will probably
need its own.

The Atom processor and anything based on NetBurst is completely
different. So are the non-Intel chips.
