94fc6ae36a 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.

046d2ca2ab Better support for AVX, AVX2, BMI1 and BMI2 instruction set detection. 
- Detect AVX and AVX2 on both Intel and AMD CPUs
- Detect BMI1 and BMI2 instruction sets (BMI2 is only on Haswell, BMI1 is
  also present on Bulldozers).
- Fix tests to reflect changes.
