Always dump generated distance vectors

Browse Source 
There's special-casing for equal access functions which bypasses
printing the distance vectors.  The following makes sure we print
them always which helps debugging.

	* tree-data-ref.cc (build_classic_dist_vector): Move
	distance vector dumping to single caller ...
	(subscript_dependence_tester): ... here, dumping always
	when we succeed computing it.
