Nice! LGTM with one minor



================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:38573
+        DAG.computeKnownBits(Op.getOperand(1), DemandedElts, Depth + 1);
+    auto Res = Opc == X86ISD::PCMPEQ ? KnownBits::eq(KnownLhs, KnownRhs)
+                                     : KnownBits::sgt(KnownLhs, KnownRhs);
----------------
(style) Don't use auto
