[committed 4/5] libstdc++: Ensure c++NN effective-target present in more tests

[Jonathan Wakely via Gcc-patches]

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.

Tested powerpc64le-linux, committed to trunk.
