libstdc++: Optimize is_reference

Instead of defining is_reference in terms of is_[lr]value_reference,
just define it directly.

libstdc++-v3/ChangeLog:

* include/std/type_traits (is_reference): Make the primary
template derive from false_type.  Define two partial
specializations that derive from true_type.
