Log Message:
Pull up following revision(s) (requested by riz in ticket #171):

        sys/arch/x86/x86/identcpu.c: revision 1.47
Force x86_xsave_features to 0 when running under XEN.
This prevents the use of xsave and xrstor thus fixing
the problem in PR/49150.  The basic problem is that the way AMD
implements those instructions means that information can leak
between domains so XEN treats them as privileged.
