* loop-unroll.c (unroll_loop_constant_iterations): Add
update of loop->nb_iterations_upper_bound I missed in my previous
commit; use TRUNC_DIV_EXPR instead of FLOOR_DIV_EXPR to divide
iteration count.
(decide_unroll_runtime_iterations): Avoid overflow.
(unroll_loop_runtime_iterations): Use TRUNC_DIV_EXPR instead of
FLOOR_DIV_EXPR to update iteration bounds.
(decide_peel_simple): Avoid integer overflow when deciding
on number of peelings.
(decide_unroll_stupid): Likewise.
