[PATCH 2/4] Fix undefined behaviour in libstdc++ testsuite

[Jonathan Wakely]

This one just fixes some missing returns, where the functions should
have been declared to return void anyway.
   Fix missing returns in libstdc++ testsuite
   
   	* testsuite/24_iterators/container_access.cc: Fix missing returns.
        * testsuite/24_iterators/range_access_cpp14.cc: Likewise.

Tested powerpc64-linux, committed to trunk.
