I just checked what icc does to the loop in __cmath_power() and it is not
able to unroll it, too. I suspect this loop is already obfuscation of the
library to some degree then :)

But icc has the same problem with std::pow(T, int) due to similar
implementation. It does optimize ::pow(T, int) though, as we do.
