[pushed] c++: add -fno-modules to some tests

[Jason Merrill]

Tested x86_64-pc-linux-gnu, applying to trunk.

-- 8< --

These tests in the modules/ directory specifically want to test
behavior without modules enabled, so let's make that explicit.

gcc/testsuite/ChangeLog:

        * g++.dg/modules/cpp-1.C
        * g++.dg/modules/cpp-3.C
        * g++.dg/modules/cpp-4.C: Specify -fno-modules.
