A few tests fail for me in my local build since this commit

Lower/OpenMP/parallel-sections.f90
Lower/OpenMP/taskgroup.f90
Lower/OpenMP/teams.f90

But I see the aarch64 buildbot is green: https://lab.llvm.org/buildbot/#/builders/173 so perhaps this is a problem on my end. Do you have any idea where I should look?

Or has anyone else come across the same problem?
