* tree.h (OMP_CLAUSE__CONDTEMP__ITER): Define.
	* gimplify.c (gimplify_scan_omp_clauses): Allow lastprivate conditional
	on OMP_SIMD if not nested inside of worksharing loop that also has
	lastprivate conditional clause for the same decl.
	(gimplify_omp_for): Add _condtemp_ clauses to OMP_SIMD if needed.
	* omp-low.c (scan_sharing_clauses): Handle OMP_CLAUSE__CONDTEMP_ also
	on simd.
	(lower_rec_input_clauses): Likewise.  Handle lastprivate conditional
	on simd construct.
	(lower_lastprivate_conditional_clauses): Handle lastprivate conditional
	on simd construct.
	(lower_lastprivate_clauses): Likewise.
	(lower_omp_sections): Call lower_lastprivate_conditional_clauses before
	calling lower_rec_input_clauses.
	(lower_omp_for): Likewise.
	(lower_omp_1): Use first rather than second OMP_CLAUSE__CONDTEMP_
	clause on simd construct.
	* omp-expand.c (expand_omp_simd): Initialize cond_var if
	OMP_CLAUSE__CONDTEMP_ clause is present.

	* c-c++-common/gomp/lastprivate-conditional-2.c (foo): Don't expect
	a sorry on lastprivate conditional on simd construct.
	* gcc.dg/vect/vect-simd-6.c: New test.
	* gcc.dg/vect/vect-simd-7.c: New test.
