StridedSlice OP has no effect if,

1. Static Shape : begin_const[idx] is 0 AND strides_const[idx] is (not 1 OR input_dimension[idx])
2. Dynamic Shape : begin_const[idx] is 0 AND strides_const[idx] is not 1

StridedSlice OP has effect if,

1. begin_const[idx] is 0 AND input_shape[idx] are equal to end_shape[idx]

Implements logo::Pass.
