The following code gives a weird warning regarding using a wrong version of

BTW, the AVX-512 version of this "bug" also compiles with ICC and Clang 4.

Right, this could be considered a user bug. However, we ran into this as we are
successfully using this code sequence in our code:

I again reduced the issue we ran into, this time I have a reproducer that fails
when compiling with -O3.

Ok I isolated the issue, please see attached reproducer. The bug is quite
delicate. Removing some unused variables in the code, and further minor
adjustments easily let the bug disappear.

Ok with binutils.x86_64 2.25.1-22.base.el7 this works. Now I have an internal
compiler error, will try to isolate this too.

This intrinsic is documented here:

This is supported by latest ICC and Clang.

Ok that one is in the SVML and only supported by ICC, not by Clang:

For AVX512 the Intel Intrinsics guide also mentioned the _mm512_undefined as
alias for _mm512_undefined_ps.
