The crash happens because the cast for `Mask = cast<ShuffleVectorSDNode>(Res)->getMask();` fails for node `t197: v16i8 = vector_shuffle<16,17,18,19,4,5,6,7,8,9,10,11,u,u,u,u> t196, t196`. However, both `LHS` and `RHS` are the same node, so `DAG.getCommutedVectorShuffle` doesn't return a `ShuffleVectorSDNode` and crashes. The fix is to add a check before the cast is performed.
