tree-optimization/121338 - UBSAN error in adjust_setup_cost
The following avoids possibly overflowing adds for rounding. We

PR tree-optimization/121338
* tree-ssa-loop-ivopts.cc (avg_loop_niter): Return an
unsigned.
(adjust_setup_cost): When niters is so large the division
result is one or zero avoid it.
(create_new_ivs): Adjust.
