<pre>
    The OpenMP spec may allow "a common block name (enclosed in slashes)."
```
% cat foo.f90
  common /c/ x
  real :: x
  !$omp flush(/c/)
end
% flang foo.f90
% flang -fopenmp foo.f90
flang-21: warning: OpenMP support in flang is still experimental [-Wexperimental-option]
error: Semantic errors in foo.f90
./foo.f90:3:16: error: Internal: no symbol found for 'c'
    !$omp flush(/c/)
                 ^
```
Does the `Internal` signal that this is not-yet-implemented?  If so, please change the message to include the phrase "not yet implemented:".  Thanks!
