MachineModel: Add a ProcResGroup class.
This allows abitrary groups of processor resources. Using something in
a subset automatically counts againts the superset. Currently, this
only works if the superset is also a ProcResGroup as opposed to a
SuperUnit.
This allows SandyBridge to be expressed naturally, which will be
checked in shortly.
