libstdc++: the specialization atomic_ref<bool> should use the primary template

Browse source 
Per [atomics.ref.int] `bool` is excluded from the list of integral types
for which there is a specialization of the `atomic_ref` class template
and [Note 1] clearly states that `atomic_ref<bool>` "uses the primary
template" instead.

libstdc++-v3/ChangeLog:

	* include/bits/atomic_base.h (__atomic_ref): Do not use integral
	specialization for bool.
