Hmm, right. Even though XSAVE could be migrated as a blob, QEMU
marshals and unmarshals the registers out and back into the xsave data,
so that unknown features are indeed unmigratable.
But are the property names necessary? It makes no sense to
enable/disable XSAVE components separately from the other CPUID bits
that enable them. Could we just mark all unknown features as
unmigratable without giving them names?
