    libstdc++: Ensure c++NN effective-target present in more tests
    
    Add effective-target keywords to tests that would fail for certain
    standard modes without the -std=gnu++NN option.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/18_support/set_terminate.cc: Require C++11 or
            higher.
            * testsuite/28_regex/simple_c++11.cc: Likewise.
            * testsuite/tr1/headers/c++200x/complex.cc: Likewise.
            * testsuite/24_iterators/headers/iterator/synopsis.cc:
            Require C++14 or lower.
