[Bug tree-optimization/19401] Trivial loop not unrolled

In 3.4 one was able to do this by specifying -fpeel-loops and got complete loop
peeling enabled.  In 4.0 this is also the case, but only for the RTL unroller -
the tree unroller is not affected and as such _this_ unrolling does not help
PR11706.  - Just another datapoint.
