LGTM with one minor - thanks.



================
Comment at: lib/Target/X86/X86ISelLowering.cpp:29017
+  case MVT::v32i1:
+    if (!Subtarget.hasInt256())
+      return SDValue();
----------------
Possibly add a TODO about handling pre-AVX2 cases (split with 2 16i8 MOVMSK) - add a SSE/AVX1 test with current codegen as well if you can.
