    tree-optimization/103987 - guard DSE modref query

    This adds a missing guard for a pointer to the DSE modref query,
    otherwise we can end up invoking APIs desired to only work on
    pointers on non-pointers when there are mismatches between declared
    and actual arguments of functions in the program.
