[Bug tree-optimization/18800] [4.0 Regression] ivopt missed

The problem is unrelated to the fact that the array is local.  It is a problem
in the algorithm that tries to find a suitable set of ivs -- it gets stuck in a
local optimum, thus causing a suboptimal code as a result.  I am testing a patch.
