Add ATTRIBUTE_NORETURN in a bunch of places: 

* cppalloc.c (memory_full): Mark function prototype with
	ATTRIBUTE_NORETURN.
	* demangle.h (collect_exit): Likewise.
	* fix-header.c (v_fatal, fatal): Likewise.
	* gcc.c (pfatal_with_name, pfatal_pexecute, fatal, fancy_abort):
	Likewise.
	* gcov.c (print_usage): Likewise.
	* genattr.c (fatal, fancy_abort): Likewise.
	* genattrtab.c (fatal, fancy_abort): Likewise.
	* gencodes.c (fatal, fancy_abort): Likewise.

	* genemit.c (fatal, fancy_abort): Likewise.
	* genextract.c (fatal, fancy_abort): Likewise.
	* genflags.c (fatal, fancy_abort): Likewise.
	* genopinit.c (fatal, fancy_abort): Likewise.
	* genoutput.c (fatal, fancy_abort): Likewise.
	* genpeep.c (fatal, fancy_abort): Likewise.
	* genrecog.c (fatal, fancy_abort): Likewise.
	* libgcc2.c (__eprintf, __default_terminate, __sjthrow,
	__sjpopnthrow, __throw): Likewise.
	* objc/objc-act.c (objc_fatal): Likewise.
	* protoize.c (usage, aux_info_corrupted,
	declare_source_confusing): Likewise.
	* rtl.c (dump_and_abort): Likewise.
