[PATCH] Add c++11 effective target to tests for C++11 features

[Jonathan Wakely]

This prevents these tests from failing when run with -std=gnu++98

	* testsuite/20_util/tuple/67844.cc: Require c++11 effective target.
	* testsuite/20_util/tuple/cons/nested_tuple_construct.cc: Likewise.
	* testsuite/27_io/rvalue_streams.cc: Likewise.

Tested x86_64-linux, committed to trunk.
