re PR c++/40308 (Brace initialization fails for member initializers in constructor for class templates)

	PR c++/40308
	PR c++/40311
	* typeck.c (cp_build_modify_expr): Always pass init-lists to the
	conversion code.
	* call.c (implicit_conversion): Allow init-list conversion to scalar
	during direct-initialization, too.  Mark the conversion bad if it
	has too many levels of braces.
	(convert_like_real): And give a helpful error.
