libstdc++: Make _GLIBCXX_NODISCARD work for C++11 and C++14
The _GLIBCXX_NODISCARD macro only expands to [[__nodiscard__]] for C++17
and later, but all supported compilers will allow us to use that for
C++11 and C++14 too. Enable it for those older standards, to give
improved diagnostics for users of those older standards.
libstdc++-v3/ChangeLog:
* include/bits/c++config (_GLIBCXX_NODISCARD): Expand for C++11
and C++14.
* testsuite/22_locale/locale/cons/12438.cc: Adjust dg-warning to
expect nodiscard warnings for C++11 and C++14 as well.
