c++: class scope function lookup [PR105908]

Browse Source 
In r12-1273 for PR91706, I removed the code in get_class_binding that
stripped BASELINK.  This testcase demonstrates that we still need to strip
it in outer_binding before putting the overload set in IDENTIFIER_BINDING,
for compatibility with bindings added directly for declarations.

	PR c++/105908

gcc/cp/ChangeLog:

	* name-lookup.cc (outer_binding): Strip BASELINK.

gcc/testsuite/ChangeLog:

	* g++.dg/cpp0x/trailing16.C: New test.
