[boost] boost/type_traits/detail/bool_trait_def.hpp

It seems to me that which type traits headers choose to #include the
corresponding bool_trait_undef.hpp is inconsistent.  I just changed
some #includes and suddenly started seeing very mysterious errors
because the corresponding macros were undefined.  Should we add some
checks to make sure neither header is #included twice in a row
without the other header intervening?
