LLVM error (simd / LoopVectorization) #724
Description
When I compile my project in Ubuntu or Windows, it fails with the following error. It compiles in MacOS though.
- PackageCompiler: compiling nonincremental system image

I'm automatically compiling my fairly large project using github actions for Linux, Window and MacOS. The automatic Linux and Windows compilations started to crash some months ago. Unfortunately, I didn't save the Manifest.toml files of successful runs, because I'm suspecting some dependency updated and is causing this problem.
I tried Ubuntu 20.04 and 22.04, Windows 2019, Windows 2022 and local Windows 10, each with the Julia versions 1.6, 1.7, 1.8 and nightly and all produced the same error.
I don't use LoopVectorization (which seems to be related to the error) directly in my fairly large project, but through a dependency.
Maybe someone can tell from the error message what the problem might be. Otherwise, in case it would help, I can try to provide a minimal example that produces this error.
