I think it'd be nicer for readability if we only include this when it's different, ie:
```c++
      OS << "  Element Type: " << getElementTypeName(Typed.ElementTy);
      if (Typed.ElementTy != Typed.DXILStorageTy)
        OS << " (stored as " << getElementTypeName(Typed.DXILStorageTy) << ")";
      OS << "\n";
```

Either way, please add a case to `llvm/test/Analysis/DXILResource/buffer-frombinding.ll` that exercises this code.
