PR tree-opt/18181
* tree-vectorizer.c (slpeel_tree_peel_loop_to_edge): Peeling scheme
changed to suppoer uses-after-loop and to void creating flow paths
that shouldn't exist.
(slpeel_update_phi_nodes_for_guard): Takes additional two arguments.
Modified to fit the new peeling scheme. Avoid quadratic behavior.
(slpeel_add_loop_guard): Takes additional argument.
(slpeel_verify_cfg_after_peeling): New function.
(vect_update_ivs_after_vectorizer): Takes additional argument. Updated
documentation. Use 'exit-bb' instead of creating 'new-bb'.
(rename_variables_in_bb): Don't update phis for BBs out of loop, to fit
the new peeling scheme.
(copy_phi_nodes): Function removed. Its functionality moved to
update_phis_for_duplicate_loop.
(slpeel_update_phis_for_duplicate_loop): Functionality of copy_phi_nodes
moved here. Added documentation. Modified to fit the new peeling scheme.
(slpeel_make_loop_iterate_ntimes): Setting loop->single_exit not not
needed - done in slpeel_tree_peel_loop_to_edge.
(slpeel_tree_duplicate_loop_to_edge_cfg): Debug printouts compacted.
(vect_do_peeling_for_loop_bound): Add documentation. Call
slpeel_verify_cfg_after_peeling. Call vect_update_ivs_after_vectorizer
with additional argument.
(vect_do_peeling_for_alignment): Call slpeel_verify_cfg_after_peeling.
(vect_finish_stmt_generation): Avoid 80 column oveflow.
