      Add several interfaces for Tensor class · ca39515e
      fengjiayi 提交于
      1. Add member variable 'DDim dims_' and a getter function 'dims()'.
      'dims' is supposed to hold tensor's shape during Op::InferShape.
      2. Remove 'mutable_data' which use default Place. User must specify a
      explicit Place when call 'mutable_data'.
      3. A PlaceHolder may be shared by more than one tensor, and some of them may be the others' slices. So we add a new member variable 'offset_' for Tensor, which is used to show the byte offset between PlaceHolder::ptr_ and where tensor's data really begins.
      4. Add functions 'ShareDataFrom' and 'Slice' for Tensor.
      
      TODO: Tensor needs a 'CopyFrom' function.
