    libstdc++: Rename test type to avoid clashing with std::any
    
    When PCH are enabled this test file includes <any> and so the
    using-directive brings std::any into the global scope. It isn't
    currently a problem, because the -std option in the dg-options means
    that PCH is not used. If that option is removed, the test fails with PCH
    and passes without.
    
    This just renames the type to avoid the name classh (and also the 'none'
    type for consistency).
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/20_util/variant/compile.cc: Rename 'any' to avoid
            clash with std::any.
