* 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.
