It gets more difficult to maintain this doesn't do any changes late
(see followups), so kill it.
* tree-vectorizer.h (vect_determine_partial_vectors_and_peeling):
Remove.
* tree-vect-loop.cc (vect_determine_partial_vectors_and_peeling):
Make static.
* tree-vect-loop-manip.cc (vect_do_peeling): Do not call it.
