[Bug tree-optimization/31040] unroll/peel loops not aggressive enough

[rguenth at gcc dot gnu dot org]

Note that in addition to unrolling the outermost loop you can experiment with
adjusting the --param max-completely-peeled-insns param.  Also I wonder if

  DO lxb=0,0

is really common (if so, the frontend might want to lower this differently).
