Pull up following revision(s) (requested by msaitoh in ticket #344):

        sys/arch/x86/include/specialreg.h: revision 1.154
        sys/arch/x86/include/specialreg.h: revision 1.155
        usr.sbin/cpuctl/arch/i386.c: revision 1.107
        sys/arch/x86/x86/procfs_machdep.c: revision 1.34

- Add definitions of AMD's CPUID Fn8000_001f Encrypted Memory features.
- Add definition of AMD's CPUID Fn8000_000a %edx bit 11 "GMET".
- Define CPUID_AMD_SVM_PFThreshold correctly.
- Modify comment a bit for consistency.

 Fix AMD Fn8000_0001f %eax bit 0's name.

Add rdpru.
