Improved parsing of brand strings for both Pineview and Cedarview
Atoms.
Add tests for both the Pineview Atom, and also Broadwell-E
(forgotten in a previous commit).
The test is a snapshot of a Haswell i7 (a.k.a. "Crystalwell") core.
This is the only test in the test DB right now which has lines for
L4 cache size, associativity and cacheline size different than "-1".
Also update create_test.py to accommodate for the new fields.
According to wikipedia, cpu-world and some cpu-z screenshots, these processors
do have a code name and it's willamette, northwood, prescott or cedar mill

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.
- 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.
- Atom Dual-core (Diamondville) is renamed to just Atom (Diamondville)
- The test with Atom D425 is named "Pineview", while the one with
Atom D525 was incorrectly named "Cedarview". Moving the latter to
atom-pineview-2.test and fixing its codename.
Instead of one big pile of tests in tests_stash.txt, keep each CPU
example raw data/parsed data in a file, ordered in a tree by
manufacturer and microarchitecture. The 64 .test files have been
extracted from tests_stash.txt. The add_test script is changed to
create_test and it doesn't append to test_stash.txt, instead it
spits out data to be saved in a .test file.
run_tests.py is not refactored yet, to be done in a subsequent commit.
