	(gfc_init_kinds): Allow TFmode.
	(gfc_build_real_type): Mark __float128 types as such.
	(gfc_init_types): Initialize float128_type_node and
	complex_float128_type_node
	* f95-lang.c (gfc_init_builtin_functions): Adjust for new
	argument of OTHER_BUILTIN macro.
	* trans-intrinsic.c (gfc_intrinsic_map_t): Likewise.
	(builtin_decl_for_precision): Special case for __float128.

	(define_quad_builtin): New function.
	(gfc_build_intrinsic_lib_fndecls): Create all __float128
	library decls if necessary. Store them in the real16_decl and
	complex16_decl builtin map fields.
	(gfc_get_intrinsic_lib_fndecl): Handle q-suffixed __float128
	library function names.
