+1 for Transpose to run super resolution example of MXNet.

I want following operators to run chainer-chemistry implementation of GGNN.

• Gather operator and int32 tensors (c.f. #41)
  • The use of them can be avoided if we input one-hot vectors instead of int32 tensors, and I take this approach for ONNX file I attached to #89. But int32 tensors is more concise and desirable.
• Transpose operator
• Identity operator
  • Chainer's copy function is exported as Identity operator (c.f. https://github.com/chainer/onnx-chainer/pull/27 ). But the use of Identity could eliminated if we transform ONNX file.

@Hakuyume Sigmoid, Transpose, Mul, Conv(dilation > 1) are now available on mkldnn_with_generic_fallback backend. Please check.
