Modify the table matcher a bit. Put some weights on the different fields.

Priously all fields in the matchtable were treated equal in importance.
With this change, the cache size a taken with half the weight in the decision.

Also add detection entries for some more recent Haswells, and the respective
tests. These are an i5 Haswell from a Mac Book Pro, and a i7 Haswel from
Thinkpad T540.
