    selftest: Move C-specific tests to c_family
    
    When trying to make use of the selftest framework over on the rust
    frontend, we ran into issues where rust1 was expected to produce errors
    containing C-like type names such as `int`.
    
    I had gotten in contact with David Malcolm on the gcc mailing list [1],
    who advised moving some test functions to a better location. The
    offending functions have also been renamed in order to better fit the C
    family of tests, and are thus not called when performing general
    selftests anymore.
    
    Kindly,

            * c-common.cc (c_family_tests): Call the new tests.
            * c-common.h (c_diagnostic_tests): Declare.
            (c_opt_problem_cc_tests): Likewise.
    
    gcc/
            * diagnostic.cc (diagnostic_cc_tests): Rename to...
            (c_diagnostic_cc_tests): ...this.
            * opt-problem.cc (opt_problem_cc_tests): Rename to...
            (c_opt_problem_cc_tests): ...this.
            * selftest-run-tests.cc (selftest::run_tests): No longer run
            opt_problem_cc_tests or diagnostic_cc_tests.
            * selftest.h (diagnostic_cc_tests): Remove declaration.
            (opt_problem_cc_tests): Likewise.
