* cfgloop.h (record_niter_bound): Declare.
* tree-ssa-loop-niter.c (record_niter_bound): Export.
Update the estimation with the upper bound here...
(estimate_numbers_of_iterations_loop): ... instead of here.
Do not forcefully reset a recorded upper bound.
* tree-vect-loop-manip.c (vect_do_peeling_for_alignment):
Record the maximum number of loop iterations of the
prologue loop.
