Drive-by changes: - Consistently mark `std::__inplace_merge::__inplace_merge_impl` `_LIBCPP_CONSTEXPR_SINCE_CXX26`. - This function template is only called by other functions that becomes constexpr since C++26, and it itself calls `std::__inplace_merge` that is constexpr since C++26. - Unblock related test coverage in constant evaluation for `stable_partition`, `ranges::stable_sort`, `std::stable_sort`, `std::stable_partition`, and `std::inplace_merge`.
