I thought we already did that, though perhaps in the old alias code.

Yes, in fact I remember having this problem last year, or one like it:

        * cse.c (note_mem_written): Varying structure memory access with
        AND address can alias scalars.
        * sched.c (true_dependence, anti_dependence, output_dependence):
        Likewise.
