	* gimplify.c (gimplify_omp_for): For #pragma omp for simd iterator
	not mentioned in clauses use private clause if the iterator is
	declared in #pragma omp for simd, and when adding lastprivate
	instead, add it to the outer #pragma omp for too.  Diagnose
	if the variable is private in outer context.  For simd collapse > 1
	loops, replace all iterators with temporaries.
	* omp-low.c (lower_rec_input_clauses): Handle LINEAR clause the
	same even in collapse > 1 loops.

	* c-parser.c (c_parser_omp_for_loop): For
	#pragma omp parallel for simd move lastprivate clause from parallel
	to for rather than simd.

	* parser.c (cp_parser_omp_for_loop): For
	#pragma omp parallel for simd move lastprivate clause from parallel
	to for rather than simd.
