[Committed] Fix Fortran testsuite failures

[Steve Kargl]

I've committed the attached patch, which fixes a few testsuite
failures related to changes in how gfortran handles legacy code.

2018-05-21  Steven G. Kargl  <ka...@gcc.gnu.org>

        * gfortran.dg/graphite/block-2.f: Adjust testcase for new gfortran
        warnings for deleted and obsolescent features.
        * gfortran.dg/graphite/id-19.f: Ditto.
        * gfortran.dg/graphite/id-20.f: Ditto.
        * gfortran.dg/graphite/id-27.f90: Ditto.
        * gfortran.dg/graphite/pr82449.f: Ditto.

PS: Yes, I forgot a ChangLog entry.  I'll commit that in a minute.
