	* testsuite/29_atomics/atomic_flag/cons/default.cc: Avoid -Wall
	warnings.
	* testsuite/29_atomics/atomic_flag/cons/aggregate.cc: Likewise.
	* testsuite/29_atomics/headers/cstdatomic/types_std_c++0x.cc:
	Likewise.
	* testsuite/29_atomics/headers/stdatomic.h/types.c: Likewise.
	* testsuite/util/testsuite_common_types.h (struct assignable,
	struct default_constructible, struct copy_constructible,
	struct explicit_value_constructible): Use a tad of simulated
	concept checking techniques to avoid spurious warnings.
	* testsuite/29_atomics/atomic/cons/assign_neg.cc: Adjust dg-error
	markers.
	* testsuite/29_atomics/atomic/cons/copy_neg.cc: Likewise.
