  Log Message:
  -----------
  Avoid unnecessary output buffer allocation and initialization.

The sparse tensor code generator allocates memory for the output tensor. As
such, we only need to allocate a MemRefDescriptor to receive the output tensor
and do not need to allocate and initialize the storage for the tensor.
