I checked this again and I just have a couple of minimal nits at this point. Flang/OpenMP changes LGTM, though I'm not familiar enough with the `DirectiveEmitter` to comment on it (maybe @alexey-bataev can comment on these changes or tag a suitable reviewer, since he reviewed similar changes before).
