e6b217b8dd bug #1652: implements a much more accurate version of vectorized sin/cos. This new version achieve same speed for SSE/AVX, and is slightly faster with FMA. Guarantees are as follows: 
- no FMA: 1ULP up to 3pi, 2ULP up to sin(25966) and cos(18838), fallback to std::sin/cos for larger inputs
  - FMA: 1ULP up to sin(117435.992) and cos(71476.0625), fallback to std::sin/cos for larger inputs

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.

72c0bbe2bd Simplify handling of tests that must fail to compile. 
Each test is now a normal ctest target, and build properties (compiler+flags) are preserved (instead of starting a new build-dir from scratch).
