* Makefile.in (tree-ssa-copy.o): Add $(CFGLOOP_H) dependency.
* tree-ssa-copy.c (init_copy_prop): Do not propagate through
single-argument PHIs if we are in loop-closed SSA form.
* tree-vect-loop-manip.c (slpeel_add_loop_guard): Pass extra guards
for the pre-condition.
(slpeel_tree_peel_loop_to_edge): Likewise.
(vect_build_loop_niters): Take an optional sequence to append stmts.
(vect_generate_tmps_on_preheader): Likewise.
(vect_do_peeling_for_loop_bound): Take extra guards for the
pre-condition.
(vect_do_peeling_for_alignment): Adjust. Unconditionally apply
the cost model check.
(vect_loop_versioning): Take stmt and stmt list to put pre-condition
guards if we are going to peel. Do not apply versioning in that
case.
* tree-vectorizer.h (vect_loop_versioning): Adjust declaration.
(vect_do_peeling_for_loop_bound): Likewise.
* tree-vect-loop.c (vect_transform_loop): If we are peeling for
loop bound only record extra pre-conditions, do not apply loop
versioning.
