        * gfortran.h: Extend struct gfc_iterator for loop annotations.
        * array.c (gfc_copy_iterator): Copy loop annotations by IVDEP,
        VECTOR, and NOVECTOR pragmas.
        * decl.c (gfc_match_gcc_ivdep, gfc_match_gcc_vector)
        (gfc_match_gcc_novector): New matcher functions handling IVDEP,
        VECTOR, and NOVECTOR pragmas.
        * match.h: Declare prototypes of matcher functions handling IVDEP,
        VECTOR, and NOVECTOR pragmas.
        * parse.c (decode_gcc_attribute, parse_do_block)
        (parse_executable): Decode IVDEP, VECTOR, and NOVECTOR pragmas;
        emit warning for unrecognized pragmas instead of error.
        * trans-stmt.c (gfc_trans_simple_do, gfc_trans_do): Add code to
        emit annotations for IVDEP, VECTOR, and NOVECTOR pragmas.
        * gfortran.texi: Document IVDEP, VECTOR, and NOVECTOR pragmas.
