* tree-scalar-evolution.h (number_of_exit_cond_executions): Remove.
* tree-scalar-evolution.c (number_of_exit_cond_executions): Likewise.
* tree-vectorizer.h (LOOP_PEELING_FOR_ALIGNMENT): Rename to ...
(LOOP_VINFO_PEELING_FOR_ALIGNMENT): ... this.
(NITERS_KNOWN_P): Fold into ...
(LOOP_VINFO_NITERS_KNOWN_P): ... this.
(LOOP_VINFO_PEELING_FOR_NITER): Add.
* tree-vect-loop-manip.c (vect_gen_niters_for_prolog_loop):
Use LOOP_VINFO_PEELING_FOR_ALIGNMENT.
(vect_do_peeling_for_alignment): Re-use precomputed niter
instead of re-emitting it.
* tree-vect-data-refs.c (vect_enhance_data_refs_alignment):
Use LOOP_VINFO_PEELING_FOR_ALIGNMENT.
* tree-vect-loop.c (vect_get_loop_niters): Use
number_of_latch_executions.
(new_loop_vec_info): Initialize LOOP_VINFO_PEELING_FOR_NITER.
(vect_analyze_loop_form): Simplify.
(vect_analyze_loop_operations): Move epilogue peeling code ...
(vect_analyze_loop_2): ... here and adjust it to compute
LOOP_VINFO_PEELING_FOR_NITER.
(vect_estimate_min_profitable_iters): Use
LOOP_VINFO_PEELING_FOR_ALIGNMENT.
(vect_build_loop_niters): Emit on the preheader.
(vect_generate_tmps_on_preheader): Likewise.
(vect_transform_loop): Use LOOP_VINFO_PEELING_FOR_NITER instead
of recomputing it. Adjust.
