* 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.
