Function VectorShiftLeft

tensorflow/lite/kernels/internal/tensor_utils.h:225–230

// Shift left a vector in place with v_size size.
template <typename T>

  // When copying overlapping ranges, std::copy is appropriate when beginning of
  // the destination range is outside the source range.

}

// Reduce-sum on a float input vector:
// input_vector: float pointer to input vector.
