[libc++] Remove various C++03 feature test macros Summary: Libc++ still uses per-feature configuration macros when configuring for C++11. However libc++ requires a feature-complete C++11 compiler so there is no reason to check individual features. This patch starts the process of removing the feature specific macros and replacing their usage with `_LIBCPP_CXX03_LANG`. This patch removes the __config macros: * _LIBCPP_HAS_NO_TRAILING_RETURN * _LIBCPP_HAS_NO_TEMPLATE_ALIASES * _LIBCPP_HAS_NO_ADVANCED_SFINAE * _LIBCPP_HAS_NO_DEFAULT_FUNCTION_TEMPLATE_ARGS * _LIBCPP_HAS_NO_STATIC_ASSERT As a drive I also changed our C++03 static_assert to use _Static_assert if available. I plan to commit this without review if nobody voices an objection.
