* tree-vectorizer.c (slpeel_add_loop_guard): Gimplify the condition.
(set_prologue_iterations): New. Set the prologue iterations to total
number of scalar iterations if the cost model check indicates that
scalar code should be generated.
(slpeel_tree_peel_loop_to_edge): Add a new parameter and code for
generating the cost condition for epilog. Call
set_prologue_iterations to generate cost condition for prolog.
(new_loop_vec_info): Initialize LOOP_VINFO_NITERS_UNCHANGED.
* tree-vectorizer.h (LOOP_VINFO_NITERS_UNCHANGED): New.
(slpeel_tree_peel_loop_to_edge): Update declaration.
(set_prologue_iterations): New declaration.
* tree-vect-analyze.c (vect_analyze_loop_form): Update
LOOP_VINFO_NITERS_UNCHANGED.
* tree-vect-transform.c
(vect_estimate_min_profitable_iters): Add new parameter and
code to check if run time cost model test is needed.
Remove code that adds builtin vectorization cost to scalar
outside cost for the run time cost model test. If run time
cost model test is needed add the appropriate guard cost to
the scalar outside cost. The guard cost depends on whether
the guard is generated at versioning or at prolog generation
or at epilog generation. Change cost model equation to include
scalar outside cost.
(conservative_cost_threshold): New. Return the less conservative
profitability threshold between the cost model threshold and the
user defined vectorization threshold.
(vect_do_peeling_for_loop_bound): Call conservative_cost_threshold.
(vect_do_peeling_for_alignment): Same.
(vect_loop_versioning): Same.
(vect_create_cond_for_align_checks): ANDs the cost model condition
with the alignment condition.
(vect_transform_loop): Call loop versioning only when there is a
misalignment or an aliasing problem.
