gimple.h (enum gf_mask): Remove GF_OMP_FOR_SIMD...

	* gimple.h (enum gf_mask): Remove GF_OMP_FOR_SIMD, change
	GF_OMP_FOR_KIND_SIMD to a value serially after other kinds,
	divide GF_OMP_FOR_KIND_MASK, GF_OMP_FOR_COMBINED,
	GF_OMP_FOR_COMBINED_INTO, GF_OMP_FOR_GRID_PHONY,
	GF_OMP_FOR_GRID_INTRA_GROUP and GF_OMP_FOR_GRID_GROUP_ITER by two.
	* omp-grid.c (grid_process_grid_body,
	grid_eliminate_combined_simd_part): Use GF_OMP_FOR_KIND_SIMD instead
	of GF_OMP_FOR_SIMD, don't test & GF_OMP_FOR_SIMD but
	== GF_OMP_FOR_KIND_SIMD.
	* omp-low.c (build_outer_var_ref, scan_sharing_clauses,
	check_omp_nesting_restrictions, scan_omp_1_stmt,
	lower_rec_input_clauses, lower_lastprivate_conditional_clauses,
	lower_lastprivate_clauses, lower_reduction_clauses, lower_omp_scan,
	omp_find_scan): Likewise.
	* omp-expand.c (expand_omp_for): Likewise.
	* omp-general.c (omp_extract_for_data): Likewise.
