    Fortran: improve array component description in runtime error message
[PR30802]

    Runtime error messages for array bounds violation shall use the following
    scheme for a coherent, abridged description of arrays or array components
    of derived types:
    (1) If x is an ordinary array variable, use "x"
    (2) if z is a DT scalar and x an array component at level 1, use "z%x"
    (3) if z is a DT scalar and x an array component at level > 1, or
        if z is a DT array and x an array (at any level), use "z...%x"
    Use a new helper function abridged_ref_name for construction of that name.

    gcc/fortran/ChangeLog:

            PR fortran/30802
            * trans-array.cc (abridged_ref_name): New helper function.

            (array_bound_check_elemental): Likewise.
            (gfc_conv_array_ref): Likewise.
