re PR tree-optimization/44688 (Excessive code-size growth at -O3)

PR rtl-optimization/44688
* loop-iv.c (determine_max_iter): Only return max_iter.
(iv_number_of_iterations): Also use the recorded loop bound
on the maximum number of iterations.
* loop-unroll.c (decide_unroll_runtime_iterations): Use
max_iter to avoid unrolling loops that do not roll.
(decide_unroll_stupid): Likewise.
* gcc.dg/var-expand1.c: Increase array size to make unrolling
possibly profitable.
