[PATCH v2 1/2] testsuite: graphite: adapt to -std=gnu23 default change

[Sam James]

r15-5327-g55e3bd376b2214 changes the default to -std=gnu23 but these
tests now trigger -Wold-style-definition. Follow Joseph's advice
in that commit and tweak the tests accordingly.

gcc/testsuite/ChangeLog:

        * gcc.dg/graphite/id-15.c: Pass -Wno-old-style-definition.
        * gcc.dg/graphite/pr38413.c: Ditto.
        * gcc.dg/graphite/pr38510.c: Ditto.

OK for trunk?

v2 fixes the commit message and warning option name.
