    libstdc++: Fix typos in tests using macros for std::float128_t support
    
    These tests check `_GLIBCXX_DOUBLE_IS_IEEE_BINARY128` but that's never
    defined, it should be "LDOUBLE" not "DOUBLE".
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/26_numerics/complex/ext_c++23.cc: Fix typo in macro.
            * testsuite/26_numerics/headers/cmath/constexpr_std_c++23.cc:
            Likewise.
            * testsuite/26_numerics/headers/cmath/functions_std_c++23.cc:
            Likewise.
            * testsuite/26_numerics/headers/cmath/nextafter_c++23.cc:
            Likewise.
