	* cfgcleanup.c (rest_of_handle_jump2): Don't repeat
	cleanup_cfg here, either.  And don't call renumber_insns.

	* cfgrtl.c (rtl_verify_flow_info_1): Don't verify that BB_END
	and BB_HEAD are in the insn stream here.  Instead make sure
	that BB_INSN is valid on all insns.  Also, do check here that
	there are no pending branch predictions...
	(rtl_verify_flow_info): ...instead of doing it here.  Checks
	for BB_END and BB_HEAD moved from rtl_verify_flow_info_1 to
	here.
