[PATCH] D92548: [CodeGen] Check if Index's OperandNum == 0 when refineIndexType(...) is called This is a bugfix for D90942

Thanks for finding and fixing this!

Can the test be simplified by using `<4 x float>` instead of `<48 x float>`?



================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:9416
   const TargetLowering &TLI = DAG.getTargetLoweringInfo();
+  if(Index.getNumOperands() == 0)
+    return false;
----------------
Probably better to explicitly check if `Index` is not a zero/sign extend, instead of checking whether it has any operands.
