    fortran: Reuse associated_dummy memory if previously allocated [PR108923]

    This avoids making the associted_dummy field point to a new memory chunk
    if it's already pointing somewhere, in which case doing so would leak the
    previously allocated chunk.

            PR fortran/108923

    gcc/fortran/ChangeLog:

            * intrinsic.cc (get_intrinsic_dummy_arg,
            set_intrinsic_dummy_arg): Rename the former to the latter.
            Remove the return value, add a reference to the lhs as argument,
            and do the pointer assignment inside the function.  Don't do
            it if the pointer is already non-NULL.
            (sort_actual): Update caller.
