	* basic-block.h (struct loop): New fields 'first' and 'last'.
	* flow.c (flow_loops_find): Compute loop->first and loop->last.
	(flow_loops_dump): Use loop->first to check for NOTE_INSN_LOOP_BEG
	and loop->last to check for NOTE_INSN_LOOP_END.

	* predict.c (estimate_probability): Use the new FIRST and LAST fields

	missing break statements as well making some coding style modifications
	as suggested by Michael Hayes.
