add std:: to "inner_product" and "accumulate"

This only works because the "dot" function is always called with std::vector<T>::iterator as input so that "argument dependent lookup" introduces the std namespace to the function. If the dot function is called like this "dot(v.data(), v.data()+v.size(), v.data())", where "v" is a std::vector and the input are plain pointers, the compiler will not find "inner_product". The same is true for the use of "accumulate".
