Fix vect_need_peeling_or_partial_vectors_p wrt peeling for gaps

The code assuming that peeling for gaps can be elided by means of
knowing niters and prologue peeling is wrong.  Peeling for gaps
means we need an epilog.

* tree-vect-loop.cc (vect_need_peeling_or_partial_vectors_p):
When peeling for gaps we always need an epilog.
