    c++: NRVO, constexpr, lambda [PR118053]

    Here during constant evaluation we encounter a VAR_DECL with
DECL_VALUE_EXPR
    of the RESULT_DECL, where the latter has been adjusted for
    pass-by-invisible-reference.  We already had the code to deal with this, we
    just need to use it in the non-capture case of DECL_VALUE_EXPR as well.

            PR c++/118053

    gcc/cp/ChangeLog:

            * constexpr.cc (cxx_eval_constant_expression): Generalize
            DECL_VALUE_EXPR invisiref handling.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp1y/constexpr-lambda1.C: New test.
