	* sel-sched-ir.h (BND_TO): insn_t will eventually be an
	rtx_insn *.  To help with transition, for now, convert from an
	access macro into a pair of functions: BND_TO, returning an
	rtx_insn *, and...
	(SET_BND_TO): New function, for use where BND_TO is used as an
	lvalue.

	* sel-sched-ir.c (blist_add): Update lvalue usage of BND_TO to
	SET_BND_TO.
	(BND_TO): New function, adding a checked cast.
	(SET_BND_TO): New function.

	* sel-sched.c (move_cond_jump): Update lvalue usage of BND_TO to
	SET_BND_TO.
	(compute_av_set_on_boundaries): Likewise.
