// The following things are done to erase NumberType info:
// - NumberType outputs are changed to DynamicType.
// - prim::Constant nodes which are numbers get changed into 0-dim tensors of
//   the corresponding type
// - prim::TensorToNum, aten::Float, aten::Int and prim::NumToTensor nodes
//   are erased.
//
// The pass assumes that DCE will be called sometime after.
