Shall we have a single option `-fdo-concurrent-parallel=` and have the decision of whether to use OpenMP or OpenACC via `-fopenmp` and `-fopenacc`?  `-fdo-concurrent-parallel` does not make much sense without one of the latter options. I guess it's a matter of proper documentation.  If we have different flavors of this option, we would run into error cases that we'd have to handle such as `-fopenacc -fdo-concurrent-to-openmp`.
