re PR c++/7099 (G++ doesn't set the noreturn attribute on std::exit and std::abort) 


	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.

	* doc/extend.texi: Document __builtin_abort, __builtin_exit,
	__builtin__exit and __builtin__Exit.

	* java/builtins.c (initialize_builtins): Ignore the additional
	parameter to DEF_BUILTIN.  Handle more C/C++ specific junk in
	the builtins.def file.
