tree-vect-loop-manip.c (create_intersect_range_checks_index): Pass in parameter loop, rather than loop_vinfo. 

* tree-vect-loop-manip.c (create_intersect_range_checks_index): Pass
	in parameter loop, rather than loop_vinfo.
	(create_intersect_range_checks): Ditto.
	(vect_create_cond_for_alias_checks): Update call to above functions.
