Add powf bench tests Add powf() bench test with input which covers these cases: - positive base to positive exponent - exponent 0 - negative base to even exponent - exponent 1 - exponent -1 - squared - squareroot - 1 to negative exponent - -1 to negative exponent - base 0 - -1 to even exponent - small base - small exponent * benchtests/Makefile (bench-math): Add powf. * benchtests/powf-inputs: New file.
