        PR c++/89852 - ICE with C++11 functional cast with { }.
        * constexpr.c (fold_non_dependent_expr_template): New static function
        broken out of...

        * cp-tree.h (fold_non_dependent_init): Declare.
        * typeck2.c (massage_init_elt): Call fold_non_dependent_init instead
        of fold_non_dependent_expr.  Don't call maybe_constant_init.
