> This reverts parts of the changes done by 7320e051eade3f22d28f11aef9c5effe324f0b79.
> 
> The introduced `CompileCommand` is still present, but the test case is again split up into two parts, one generic (without the `MaxVectorSize` flag), and one C2 specific with that flag. This fixes the test case for C1.
> 
> We could also keep the current test structure and add `IgnoreUnrecognizedVMOptions` for the later three `run`s, but this would execute the same test case multiple times if a client VM is tested.
