re PR c++/33894 (pragma omp atomic broken)

	PR c++/33894
	* cp-tree.h: Update comment - TYPE_LANG_FLAG_0 is not
	OMP_ATOMIC_DEPENDENT_P in OMP_ATOMIC.
	* pt.c (tsubst_expr): Assert OMP_ATOMIC_DEPENDENT_P.
	* semantics.c (finish_omp_atomic): Revert most of the
	2007-02-05 changes, just keep the new representation of
	OMP_ATOMIC_DEPENDENT_P OMP_ATOMIC.

	* testsuite/libgomp.c++/atomic-1.C: New test.
