sched1: debug/model: dump predecessor list and BB num [NFC]

Browse source 
This is broken out of predecessor promotion patch so that debugging can
proceed during stage1 restrictions.

gcc/ChangeLog:
	* haifa-sched.cc (model_choose_insn): Dump unscheduled_preds.
	(model_dump_pressure_summary): Dump bb->index.
	(model_start_schedule): Pass bb.
	* sched-rgn.cc (debug_dependencies): Dump SD_LIST_HARD_BACK deps.
