    c++: constexpr VEC_INIT_EXPR [PR118285]

    cxx_eval_vec_init_1 was doing the wrong thing for an array of
    self-referential class type; just evaluating the TARGET_EXPR initializer
    creates a new object that refers to the TARGET_EXPR_SLOT, if we want it to
    refer properly to the initialization target we need to provide it.

            PR c++/118285

    gcc/cp/ChangeLog:

            * constexpr.cc (cxx_eval_vec_init_1): Build INIT_EXPR for
            initializing a class.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp0x/initlist-opt7.C: New test.
