libstdc++: Small extended float support tweaks
The following patch
1) enables the std::float128_t overloads for x86 with glibc 2.26+
2) makes std::nextafter(std::float16_t, std::float16_t) and
std::nextafter(std::bfloat16_t, std::bfloat16_t) constexpr
3) adds (small) testsuite coverage for that
2022-10-21 Jakub Jelinek <jakub@redhat.com>
* config/os/gnu-linux/os_defines.h (_GLIBCXX_HAVE_FLOAT128_MATH):
Uncomment.
* include/c_global/cmath (nextafter(_Float16, _Float16)): Make it constexpr.
If std::__is_constant_evaluated() call __builtin_nextafterf16.
(nextafter(__gnu_cxx::__bfloat16_t, __gnu_cxx::__bfloat16_t)): Similarly
but call __builtin_nextafterf16b.
* testsuite/26_numerics/headers/cmath/nextafter_c++23.cc (test): Add
static assertions to test constexpr nextafter.
