This patch uses _GLIBCXX_USE_BUILTIN_TRAIT macro instead of __has_builtin in
the type_traits header for traits that have a corresponding fallback
non-built-in implementation. This macro supports to toggle the use of built-in
traits in the type_traits header through _GLIBCXX_DO_NOT_USE_BUILTIN_TRAIT
