pow of complex<float> has some accuracy issues with AVX512.

Numpy recently merged support for accelerated simd exp/log for float32 in prs numpy/numpy#13581 and others. We seem to have hit an issue numpy/numpy#13586 with clang 7.0, have you experienced anything similar? Also, it seems glibc 2.27 has quite good support out of the box for avx. What do you think?

Hey Matti, nice to see you here. Sorry for the late reply. We will definitely look into this numpy issue.
