bc5dd4cafd PR560: Fix the AVX512f only builds 
Commit c53eececb0
 introduced AVX512 support for complex numbers but required
avx512dq to build.  Commit 1d683ae2f5
 fixed some but not, it would seem all,
of the hard avx512dq dependencies.  Build failures are still evident on
Eigen and TensorFlow when compiling with just avx512f and no avx512dq
using gcc 7.3.  Looking at the code there does indeed seem to be a problem.
Commit c53eececb0
 calls avx512dq intrinsics directly, e.g, _mm512_extractf32x8_ps
and _mm512_and_ps.  This commit fixes the issue by replacing the direct
intrinsic calls with the various wrapper functions that are safe to use on
avx512f only builds.

e79c5149bf Fix AVX512 implementations of psqrt 
This commit fixes the AVX512 implementations of psqrt in the same
way that 3ed67cb0bb
 fixed the AVX2 version of this function.  The
AVX512 versions of psqrt incorrectly return -0.0 for negative
values, instead of NaN.  Fixing the issues requires adding
some additional instructions that slow down the algorithms.  A
similar test to the one used in 3ed67cb0bb
 shows that the
corrected Packet16f code runs at 73% of the speed of the existing code,
while the corrected Packed8d function runs at 68% of the original.
