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.
