Moving data back and forth between CPUX86State and x86_def_t makes the
initialization ordering confusing (today data is moved from x86_def_t to
X86CPU, and never the other way around).
As this code is removed in the next patches, I don't mind too much, but maybe
it's simpler to implement this change only after the "use static properties for
setting cpuid features" patch?
