	PR c++/7099 
	* builtin-attrs.def: Define new attribute lists for use in 
	builtins.def. 
	* builtins.def [DEF_BUILTIN]: Modify to take an additional 
	ATTRS argument, an enumerated value defined in builtin-attrs.def 
	that represents the attribute list for the builtins.  Modify 
	all builtin functions to pass an appropriate attribute list. 
	Specify "abort", "exit", "_exit" and "_Exit" builtins here with 
	their required noreturn attributes. 
	* tree.h (enum_builtin_function): Ignore the additional parameter 
	to DEF_BUILTIN. 
	* builtins.c (built_in_names): Likewise. 
	* c-common.c: (builtin_function_2): Replace the "int noreturn_p" 
	argument with a tree representing the functions attribute list. 
	Pass this "attrs" argument to builtin_function.  No longer handle 
	the noreturn_p processing manually. 
	(built_in_attributes): Move the definitions from builtin-attrs.def 
	before c_common_nodes_and_builtins. 
	(c_common_nodes_and_builtins): Handle the new ATTRS parameter in 
	DEF_BUILTIN, passing it to both builtin_function and the changed 
	builtin_function_2.
