The old COW std::string is not usable in constant expressions, so these
new tests fail with -D_GLIBCXX_USE_CXX11_ABI=0.
The parts of the tests using std::string can be conditionally skipped.
libstdc++-v3/ChangeLog:
*
testsuite/20_util/specialized_algorithms/uninitialized_copy/constexpr.cc:
Do not test COW std::string in constexpr contexts.
*
testsuite/20_util/specialized_algorithms/uninitialized_default_construct/constexpr.cc:
Likewise.
*
testsuite/20_util/specialized_algorithms/uninitialized_fill/constexpr.cc:
Likewise.
*
testsuite/20_util/specialized_algorithms/uninitialized_move/constexpr.cc:
Likewise.
*
testsuite/20_util/specialized_algorithms/uninitialized_value_construct/constexpr.cc:
Likewise.
