Update the OpenMP section again, now that Jakub has added the 'masked' construct.
Comments?

Jakub did comment on IRC that it probably makes sense to do less
frequent commits.
Thus, I waited a while and now have an update list. Besides 'masked' it
now mentions:
scope construct; nothing and error directive + primary in proc_bind.
OK? Comments? Suggestions?
Tobias
PS: Also new that the existing 'device' clause now supports the
modifiers 'device_num' and 'ancestor' and a bunch of bug fixes. While
very useful, I think those aren't changes.html worthy.

Agreed (especially because the ancestor modifier is only parsing, but
eventually runs into sorry_at for missing reverse_offload support).
Ok, thanks.
