Move testsuite/c-c++-common/Wunused-local-typedefs-2.c to testsuite/g++.dg/warn/Wunused-local-typedefs-3.C

gcc/testsuite/

	* g++.dg/warn/Wunused-local-typedefs-3.C: Move the c++-only test
	gcc/testsuite/c-c++-common/Wunused-local-typedefs-2.c to here.

From-SVN: r191832

From-SVN: r191831

In the example of this patch, gcc/g++ invoked with
-Wunused-local-typedefs warns on dependant entities even when those
are decorated with the 'unused' attribute.

This is because in cplus_decl_attributes, save_template_attributes
makes so that the 'unused' attribute is applied to its appertaining
entity only at instantiation time.  But then at parsing time
maybe_warn_unused_local_typedefs checks for TREE_USED before warning.

This patch applies the 'unused' attribute at compilation time.

Tested on x86_64-unknown-linux-gnu against trunk.

gcc/cp/

	* decl2.c (is_late_template_attribute): "unused" attribute is to
	be applied at compile time.

gcc/testsuite/

	* c-c++-common/Wunused-local-typedefs-2.c: New test.

From-SVN: r191830

In the example of the patch, g++ fails to warn that the variable N::i
(introduced via a using declaration) is unused.

This is because as we want to emit the warning in poplevel, when we
walk the local bindings returned by getdecls, we forget that a
VAR_DECL introduced by a using declaration is represented by a
TREE_LIST which TREE_VALUE is the VAR_DECL, and we wrongly look for a
bare VAR_DECL.

Fixed thus and tested on x86_64-unknown-linux-gnu against trunk.

gcc/cp/

	* decl.c (poplevel<warn_unused*>): Do not forget that some local
	bindings are represented by a TREE_LIST.
