    Use move-aware auto_vec in map
    
    Using auto_vec rather than vec for means the vectors are release
    automatically upon return, to stop the leak. The problem seems is that
    auto_vec<T, N> is not really move-aware, only the <T, 0> specialization
    is.
    
    gcc/ChangeLog:
    
            * tree-profile.cc (find_conditions): Use auto_vec without
            embedded storage.
