function.c (diddle_return_value): Kill code to determine return value before expand_function_end.

	* function.c (diddle_return_value): Kill code to determine
	return value before expand_function_end.
	(expand_function_end): Delay call to clobber_return_register
	after fucntion return value is computed.

	Re-install temporary reverted patch:
	* toplev.c (rest_of_compilation): Call split_all_insns
	before reg-stack and shorten-branches. Do shorten-branches
	after reg-stack.
	* final.c (shorten_branches): Remove insn splitting code.
