HAX will only support SSE (128-bit) registers, while env->xmm_regs
supports AVX512 (512-bit) so you have to copy registers one by one.

Is there documentation for HAX?  In particular I'm curious as to what
the CPUID information looks like in the guest, and whether there are
ioctls to change it.  In particular I would expect XSAVE to be disabled.
