* error.c (dump_function_name): Don't let the user see __comp_ctor.

        Clean up copy-initialization in overloading code.
        * call.c (build_user_type_conversion_1): Die if we are asked to
        convert to the same or a base type.
        (implicit_conversion): Avoid doing so.  Lose reference binding code.
        (convert_like_real): Treat BASE_CONV and RVALUE_CONV as implicit
        direct-initialization.  Also do direct-init part of copy-init.
        (build_user_type_conversion): Don't provide context to convert_like.
        * cvt.c (ocp_convert): build_user_type_conversion will now provide
        the constructor call for copy-init.

        * pt.c (tsubst_decl): Call clone_function_decl here if this is an
        instantiation of a member template.
        (do_decl_instantiation): Not here.
