Jonathan Wakely 6fd4b25b50 Add noexcept-specifier to std::apply and std::make_from_tuple ... When unpacking a std::tuple we know that the std::get calls are noexcept, so only the invocation (for std::apply) and construction (for std::make_from_tuple) can throw. We also know the std::get calls won't throw for a std::array, but this patch doesn't specialize the variable template for std::array. For an arbitrary tuple-like type we don't know if the std::get calls will throw, and so just use a potentially-throwing noexcept-specifier. * include/std/tuple (__unpack_std_tuple): New variable template and partial specializations. (apply, make_from_tuple): Add noexcept-specifier. * testsuite/20_util/tuple/apply/2.cc: New test. * testsuite/20_util/tuple/make_from_tuple/2.cc: New test.
