This commit addresses a seemingly unintentional return type of the ilogb overload taking a double. Currently it returns double, while it is supposed to return int. The return types seems to be covered by libcxx/test/std/numerics/c.math/cmath.pass.cpp, but the issue would only show up if we tested with a libc that doesn't provide the ilogb(double) overload, which we don't.
