I will submit a new version of this patch later, as I will:

 * Split some changes that can be made in a separate patch, after
   the conversion (the x86_cpudef_setup() removal and the CPU listing
   code);
 * Add proper attribution to Andreas and Igor, who wrote
   "[RFC v5] target-i386: Slim conversion to X86CPU subclasses + KVM
   subclasses".
