Keith Packard via Newlib 6295d75913 newlib/libm/math: Make pow/powf return qnan for snan arg 
The IEEE spec for pow only has special case for x**0 and 1**y when x/y
are quiet NaN. For signaling NaN, the general case applies and these functions
should signal the invalid exception and return a quiet NaN.
