This patch implements built-in trait for std::is_void. Since the new built-in

Hi,
This patch series gets std::is_object to dispatch to built-in traits and
implements the following built-in traits, on which std::object depends.
* __is_reference
* __is_function
* __is_void
std::is_object was depending on them with disjunction and negation.

the type_traits header.
