Subject: gimplify.c (gimplify_scan_omp_clauses): Don't sorry_at on lastprivate
 conditional on combined for simd.

	* gimplify.c (gimplify_scan_omp_clauses): Don't sorry_at on lastprivate
	conditional on combined for simd.
	* omp-low.c (struct omp_context): Add combined_into_simd_safelen0
	member.
	(lower_rec_input_clauses): For gimple_omp_for_combined_into_p max_vf 1
	constructs, don't remove lastprivate_conditional_map, but instead set
	ctx->combined_into_simd_safelen0 and adjust hash_map, so that it points
	to parent construct temporaries.
	(lower_lastprivate_clauses): Handle ctx->combined_into_simd_safelen0
	like !ctx->lastprivate_conditional_map.
	(lower_omp_1) <case GIMPLE_ASSIGN>: If up->combined_into_simd_safelen0,
	use up->outer context instead of up.
	* omp-expand.c (expand_omp_for_generic): Perform cond_var bump even if
	gimple_omp_for_combined_p.
	(expand_omp_for_static_nochunk): Likewise.
	(expand_omp_for_static_chunk): Add forgotten cond_var bump that was
	probably moved over into expand_omp_for_generic rather than being copied
	there.
gcc/cp/
	* cp-tree.h (CP_OMP_CLAUSE_INFO): Allow for any clauses up to _condvar_
	instead of only up to linear.
gcc/testsuite/
	* c-c++-common/gomp/lastprivate-conditional-2.c (foo): Don't expect
	a sorry_at on any of the clauses.
libgomp/
	* testsuite/libgomp.c-c++-common/lastprivate-conditional-7.c: New test.
	* testsuite/libgomp.c-c++-common/lastprivate-conditional-8.c: New test.
	* testsuite/libgomp.c-c++-common/lastprivate-conditional-9.c: New test.
	* testsuite/libgomp.c-c++-common/lastprivate-conditional-10.c: New test.
