IMO the guality testsuite is not really appropriate for debug info issues, 
it's too brittle, has a low signal-over-noise ratio and nobody really cares 
about it.  And, given that most people already don't care about the regular 
gnat.dg testsuite, I think that literally nobody will about gnat.dg/guality.

Given that only AdaCore's folks work on Ada debug info issues in practice and 
that they run the GDB testsuite, I don't see any real need for it.
