Log:
        PR c++/89083, c++/80864 - ICE with list initialization in template.
        * constexpr.c (adjust_temp_type): Use copy_node and change the type
        instead of using build_constructor.
        * decl.c (reshape_init_r): Don't reshape a digested initializer.
        Return the initializer for COMPOUND_LITERAL_P.
