I accidentally backported tests using { target c++11 } to the branch,
but that only works on trunk. One test was also using C++14-only
features, but is meant to be valid in C++11.

Also committed this version to gcc-5-branch.

    Replace unsupported effective-target with dg-options
    
    	* testsuite/24_iterators/reverse_iterator/71771.cc: Replace calls to
    	C++14 std::rbegin and std::rend.  Use dg-options instead of
    	effective-target.
