    rtl-optimization/109585 - alias analysis typo

    When r10-514-gc6b84edb6110dd2b4fb improved access path analysis
    it introduced a typo that triggers when there's an access to a
    trailing array in the first access path leading to false
    disambiguation.

            PR rtl-optimization/109585
            * tree-ssa-alias.cc (aliasing_component_refs_p): Fix typo.

            * gcc.dg/torture/pr109585.c: New testcase.=
