    tree-optimization/113602 - datarefs of non-addressables

    We can end up creating ADDR_EXPRs of non-addressable entities during
    for example vectorization.  The following plugs this in data-ref
    analysis when that would create such invalid ADDR_EXPR as part of
    analyzing the ref structure.

            * tree-data-ref.cc (dr_analyze_innermost): Fail when
            the base object isn't addressable.

            * gcc.dg/pr113602.c: New testcase.
