> Build dependence information based on tagged access [1], e.g. for access:
>             MustWriteAccess :=  [Reduction Type: NONE] [Scalar: 0]
>                 [N] -> { Stmt_for_body[i0] -> MemRef_b[6 + i0] };
> we build tag it and get:
>                 [N] -> {[Stmt_for_body[i0] -> MemRef_a[]] -> MemRef_b[6 + i0] };
Why does it say MemRef_a and then MemRef_b ?
