unordered_set: Minor formatting changes. 

2011-12-12  François Dumont <fdumont@gcc.gnu.org>

	* include/profile/unordered_set: Minor formatting changes.
	(unordered_set<>::_M_profile_destruct,
	unordered_multiset<>::_M_profile_destruct): Fix implementation to not
	rely on normal implementation details anymore.
	(unordered_set<>::_M_profile_resize,
	unordered_multiset<>::_M_profile_resize): Implement consistently
	accross all unordered containers.
	(unordered_set<>::emplace, unordered_set<>::emplace_hint,
	unordered_multiset<>::emplace, unordered_multset<>::emplace_hint): Add
	to signal rehash to profiling system.
	* include/profile/unordered_map: Likewise for unordered_map<> and
	unordered_multimap<>.
