Jakub Jelinek f7468577f8 tree.h (OMP_CLAUSE_LINEAR_GIMPLE_SEQ): Define.
* tree.h (OMP_CLAUSE_LINEAR_GIMPLE_SEQ): Define.
	* gimplify.c (omp_is_private): Change last argument's type to int.
	Only diagnose lastprivate if the simd argument is 1, only diagnose
	linear if the simd argument is 2.
	(gimplify_omp_for): Adjust omp_is_private callers.  When adding
	lastprivate or private, add the clause to OMP_FOR_CLAUSES.  Pass
	GOVD_EXPLICIT to omp_add_variable.  For simd with collapse == 1
	create OMP_CLAUSE_LINEAR rather than OMP_CLAUSE_PRIVATE for var.
	If var != decl and decl is in OMP_CLAUSE_LINEAR, gimplify decl
	increment to OMP_CLAUSE_LINEAR_GIMPLE_SEQ.
	* omp-low.c (scan_sharing_clauses, lower_lastprivate_clauses): Handle
	OMP_CLAUSE_LINEAR_GIMPLE_SEQ.
	* tree-nested.c (convert_nonlocal_omp_clauses,
	convert_local_omp_clauses): Handle OMP_CLAUSE_LINEAR.

	* testsuite/libgomp.c/simd-7.c: New test.
	* testsuite/libgomp.c/simd-8.c: New test.
	* testsuite/libgomp.c/simd-9.c: New test.
	* testsuite/libgomp.c/loop-16.c: New test.
