	PR fortran/94690
        * openmp.c (OMP_DISTRIBUTE_CLAUSES): Add OMP_CLAUSE_LASTPRIVATE.
        (gfc_resolve_do_iterator): Skip the private handling for SIMD as
        that is handled by ME code.
	* trans-openmp.c (gfc_trans_omp_do): Don't add private/lastprivate
	for dovar_found == 0, unless !simple.
