[PATCH] D52426: [X86] Move X86DAGToDAGISel::matchBEXTRFromAnd() into X86ISelLowering

[Craig Topper via Phabricator via llvm-commits]

================
Comment at: lib/Target/X86/X86ISelLowering.cpp:35407
 
+  if (SDValue R = combineShiftAndIntoBEXTR(N, DAG, Subtarget))
+    return R;
----------------
This should probably be below the LegalizeOps check. We should give ample opportunity for AND based DAG combines to optimize this.
