* reload1.c (fixup_abnormal_edges): New static function.
	(reload): Use it.

	* flow.c (need_fake_edge_p): New function.
	(flow_call_edges_add): Fix handling of noreturn and sibbling calls;
	avoid call insn to be very last insn in the insn stream.

	* profile.c (branch_prob): Call flow_call_edges_add instead of
	doing that by hand; cleanup cfg to re-merge basic blocks once
	we are done.
