Why is it necessary to save/restore BNDCFGS MSR on states other
than FULL and RESET?
Yes, nothing in QEMU except reset will touch the MSR, but this applies
also to all the other MSRs that are saved unconditionally. It's nice to
be able to poke them with gdb, and saving/restoring the MSR provides that.
