	* sel-sched-ir.h (BB_NOTE_LIST): struct sel_region_bb_info_def's
	"note_list" field will eventually be an rtx_insn *.  To help with
	transition, for now, convert from an access macro into a pair of
	functions: BB_NOTE_LIST, returning an rtx_insn *, and...
	(SET_BB_NOTE_LIST): New function, for use where BB_NOTE_LIST is
	used as an lvalue.

	* sel-sched.c (create_block_for_bookkeeping): Update lvalue usage
	of BB_NOTE_LIST to SET_BB_NOTE_LIST.

	* sel-sched-ir.c (init_bb): Likewise.
	(sel_restore_notes): Likewise.
	(move_bb_info): Likewise.
	(BB_NOTE_LIST): New function, adding a checked cast to rtx_insn *.
	(SET_BB_NOTE_LIST): New function.
