Nice improvement!



================
Comment at: llvm/lib/Target/AArch64/AArch64ISelLowering.cpp:10702
+    SDValue Splice = DAG.getNode(ISD::VECTOR_SPLICE, DL, ContainerVT, NewInVec,
+                                 NewInVec, DAG.getConstant(Idx, DL, MVT::i64));
+    return convertFromScalableVector(DAG, Op.getValueType(), Splice);
----------------
I'm not sure if this really matters because it would probably reuse NewInVec anyway, but strictly this could be UNDEF.
