I think we should extract the common code to a function, such as:
```
int64_t getRealVectorRank(ShapedType shapedType, VectorType vectorType) {
  int64_t elementVectorRank = 0;
  VectorType elementVectorType =
      llvm::dyn_cast<VectorType>(shapedType.getElementType());
  if (elementVectorType)
    elementVectorRank += elementVectorType.getRank();
  return vectorType.getRank() - elementVectorRank;
}
```
The `TransferReadOp::parse`、`TransferWriteOp::parse`、`getTransferMinorIdentityMap` need invoke this function.
