Fixes interlockedbittestandreset/set in intrin_x86.h 

This doesn't update the file to the latest version from mingw32 since this is already a custom header stripped from mingw32.

This also fixes the functions for x86_64(verified that it still works for both architectures) and also updates the version inside of GSdx.
Also removes a comment in the GSdx header saying that these functions are broken since they no longer are.
