            * gfortran.texi: Document annotations IVDEP, UNROLL n, VECTOR,
            NOVECTOR as applied to DO CONCURRENT.
            * parse.cc (parse_do_block): Parse annotations IVDEP, UNROLL n,
            VECTOR, NOVECTOR as applied to DO CONCURRENT.  Apply UNROLL onl=
y to

            (gfc_trans_simple_do): Adjust.
            (gfc_trans_forall_loop): Annotate loops with IVDEP, UNROLL n,
            VECTOR, NOVECTOR as needed for DO CONCURRENT.
