    c++: add -fno-modules to some tests
    
    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.
