    tree-optimization/117333 - ICE with NULL access size DR

    dr_may_alias_p ICEs when TYPE_SIZE of DR->ref is NULL but this is
    valid IL when the access size of an aggregate copy can be infered
    from the RHS.

            PR tree-optimization/117333
            * tree-data-ref.cc (dr_may_alias_p): Guard against NULL
            access size.

            * gcc.dg/torture/pr117333.c: New testcase.
