================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:21088
+  if (StoreVT.is256BitVector()) {
+    if (StoredVal.getOpcode() != ISD::CONCAT_VECTORS || !StoredVal.hasOneUse())
+      return SDValue();
----------------
Not sure if its any use but I created the collectConcatOps helper to do something similar
