Fortran 2003 Test Suite from Oak Ridge National Lab

Hi,

This is the Fortran 2003 Test Suite that I mentioned on today’s call.

https://www.olcf.ornl.gov/for-users/software/nccs-fortran-2003-validation-suite/

Here is the direct link to the GitHub repo:

https://gitlab.com/DmitryLyakh/GFC.

The license is LGPL v3, is not as bad as GPL, but still has its own set of issues. The GitLab repo hasn’t had a commit in about a year, but I believe the author Dmitry Lyakh is still at ORNL. If the tests seem useful to have in Flang as an external dependency, we could ask Dmitry to change the license to a BSD-style license.

Take and look. Let me know what you think.
