seems that lack some operator for cpu

This fixed things for no MKL, but crashed if I enable MKL. It crashes in the concat layer. If I enable MKL, but disable MKL_EXPERIMENTAL for the concat layer it still crashes. Both crashes are attached.

@glingyan can you take a look as to why it may be crashing with MKL enabled?
