finish()

void * vn_walk_cb_data::finish	(	alias_set_type	set,
		alias_set_type	base_set,
		tree	val )

push_partial_def()

void * vn_walk_cb_data::push_partial_def	(	pd_data	pd,
		alias_set_type	set,
		alias_set_type	base_set,
		HOST_WIDE_INT	offseti,
		HOST_WIDE_INT	maxsizei )

Push PD to the vector of partial definitions returning a
value when we are ready to combine things with VUSE, SET and MAXSIZEI,
NULL when we want to continue looking for partial defs or -1
on failure.
