[NFC][Fortran/gfortran] Add script to generate static test configuration

[tarunprabhu]

This adds the script to generate the static test configuration files from the DejaGNU annotations from the test sources. The script is only intended to be used when the test files are updated from upstream.

When I ran this myself, achar_2.f90 was changed from a run to a compile test. The output complained that it could not open the file. If this cannot be reproduced on your machine then don't let it block the patch.

Otherwise, this looks good. I'm not an expert in python or dejagnu, but the code seems well structured and easy to follow. The FIXMEs seem reasonable to leave for a later date because this can already generate a test configuration that is an improvement upon what we had before.

Thank you for your work on this!

Strange. I'll check again on my end.

Thanks for taking a look. I'll leave this up over the weekend to give others a chance to review it.

LGTM. I have only a couple nits and suggestions, but feel free to ignore them.

@tblah, It seems to be working fine for me.

@luporl Thanks for the careful review.

I have reworded some of the comments in the code. Could you take a look and let me know if they are clearer now?

@tarunprabhu Thanks for taking the time for addressing my comments, everything is clearer now.
