Wflow build fails on TeamCity machines

[vers-w]

Recently the wflow builds on TeamCity are failing on both Windows and Linux machines with the following error:

05:17:12   - PackageCompiler: compiling nonincremental system image
05:27:27   LLVM ERROR: Cannot select: 0x19afdf803f0: v2f64 = X86ISD::VGETMANT 0x19afdf9b900, TargetConstant:i32<2>

This error is related to the use of the Julia package LoopVectorization, and is not reproducible on our own laptops.

It looks like another instance of #361 (comment).

The build error seems to be caused by a difference between the Loopvectorization CPU detection ("skylake-avx512") and using (in combination) other CPU targets (e.g. "generic") for the build. The build is only successful using the following cpu_target : cpu_target = "skylake-avx512". CPU on TeamCity machines supports AVX-512 instructions.
