protonspringandMarco Costalba 650aeaf242 Remove std::pow from reduction. (#2234) 
This is a functional simplification that removes the std::pow from reduction. The resulting reduction values are within 1% of master.

This is a simplification because i believe an fp addition and multiplication is much faster than a call to std::pow() which is historically slow and performance varies widely on different architectures.
