The concern IIRC is that we would overwrite the .ali files generated by
the non-debug compilation.  If compare succeeds, this shouldn't be much
of a problem, but if it fails, the file might be different, and it might
then affect other compilations.

I support the idea of adding another command-line flag that disables
writing of .ali files, and have it passed to gnat during the second
-fcompare-debug compilation (-fcompare-debug-second).
