   I am trying to work out what `offset_factor` means. I think the basic idea is right. But in detail, there're mistakes. According to xqdan, `offset_factor` has the same meaning with `y.itemsize`. But I think not. In TVM's official tutorial (https://tvm.apache.org/docs/how_to/work_with_schedules/tensorize.html), `offset_factor` is 1 in `intrin_gemv`. But at the same time, `a`, `b` and `k` all has `float32` type. So I suspect `offset_factor` means the interval (counted by the number of elements rather bytes) between two nearby elements.
