OpenMPSupport.md is for documenting feature support not extensions. However, this table is for OpenMP 4.0 support (as that is the oldest standard we do not fully support) and so I don't think `ATOMIC UPDATE COMPARE` is relevant here. Maybe we need to update the note to say which standard added that?
