* 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.
