re PR libfortran/18495 ([4.0 only] Intrinisc function SPREAD is broken)

        * intrinsics/spread_generic.c (spread):  Remove const from
        return array descriptor.
        New variables: rrank (rank of return array),  rs (for
        calculating the size of the return array), srank (rank
        of the source array).
        Generate runtime error if the dim= argument is larger than
        the rank of the return array.
        Generate runtime error if the needed rank of the return
        array is larger than 7.
        If ret->data is null, populate the return array descriptor
        and initialize the variables for the actual operation.
        Otherwise, set ret->dim[0].stride to one if it is zero.
        Change second, independent use of variable dim to srank.
