Vectorize SigmoidOp on CPU Summary: I noticed that Sigmoid was taking an inordinate amount of time in our NMT benchmark, so I looked at the implementation and it didn't seem optimal. I replaced the implementation with an Eigen version so that when the Eigen update goes through, we will get proper AVX(2) vectorization.
