Sure - let's ping Eli to make sure there are no other suggestions, but the code looks good to me.

================
Comment at: test/Transforms/InstCombine/icmp-shl-nuw.ll:54-55
+
+define <2 x i1> @icmp_ule_16x2_non_pow2_shift(<2 x i64>) {
+; CHECK-LABEL: @icmp_ule_16x2_non_pow2_shift(
+; CHECK-NEXT:    [[D:%.*]] = icmp ult <2 x i64> %0, <i64 4, i64 4>
