Still not seeing addw or xorw.

================
Comment at: test/MC/X86/I386-64.s:868
+// CHECK: tzcntl %r13d, %r13d 
+// CHECK: encoding: [0xf3,0x45,0x0f,0xbc,0xed]       
+tzcntl %r13d, %r13d 
----------------
tzcnt was added on haswell as part of BMI instructions.

================
Comment at: test/MC/X86/PPRO-64.s:115
+
+// CHECK: rdsspd %r13d 
+// CHECK: encoding: [0xf3,0x41,0x0f,0x1e,0xcd]        
----------------
rdsspd is definitley not a pentium pro instruction. That's a control flow enhancement technology instruction that was just added.
