Output of coreinfo on Wine + Ryzen1800x

There are clearly a bunch of reporting issues in Wine for Ryzen. CPU name is
wrong (not that big of a deal performance wise), but the main issue is
reporting logical cores as physical cores.

Honestly if we are reporting this wrong on AMD, we are reporting the same wrong
information in regards to SMT / hyperthreading on Intel. I suspect Intel to
benefit from a proper implementation as well.

My bet is that the core reporting is making the game do pick incorrect pinning.
I will work on patches for both issues. Not sure when I can get them ready
though. I maybe to provide a really dirty hack just to test the theory.
