According to http://winehq.org/site/docs/winedev-guide/threading, the %fs
register points to the thread environment block in Windows. For Wine to work
properly, we have to do the same. To quote Alexandre from a private email:

IMO the right fix would be for ATI to use standard glibc TLS support, which is
based on the %gs register and is compatible with Wine.

We added a check for the ATI problem here:
