* tree-vect-loop-manip.c (vect_update_epilogue_niters): New function.
Reject using vector epilogue loops for single iterations. Install
the constant number of epilogue loop iterations in the associated
loop_vinfo. Rely on vect_determine_partial_vectors_and_peeling
to do the main part of the test.
(vect_do_peeling): Use vect_update_epilogue_niters to handle
epilogue loops with a known number of iterations. Skip recomputing
the number of iterations later in that case. Otherwise, use
vect_determine_partial_vectors_and_peeling to decide whether the
epilogue loop needs to use partial vectors or peeling.
* tree-vect-loop.c (_loop_vec_info::_loop_vec_info): Set the
default can_use_partial_vectors_p to false if partial-vector-usage=0.
(determine_peel_for_niter): Remove in favor of...
(vect_determine_partial_vectors_and_peeling): ...this new function,
split out from...
(vect_analyze_loop_2): ...here. Reflect the vect_verify_full_masking
and vect_verify_loop_lens results in CAN_USE_PARTIAL_VECTORS_P
