Summary: First, this patch fixes an assert failure when, for example, "omp for" has num_teams. Second, this patch prevents duplicate diagnostics when, for example, "omp for" has uniform. This patch makes the general assumption (even where it doesn't necessarily fix an existing bug) that it is worthless to perform sema for a clause that appears on a directive on which OpenMP does not permit that clause. However, due to this assumption, this patch suppresses some diagnostics that were expected in the test suite. I assert that those diagnostics were likely just distracting to the user.
