[Bug rtl-optimization/19001] [3.4 Regression] Loops with power of two step and variable bounds not unrolled

[chris at bubblescope dot net]

Sorry, I was testing for the existance of loop-unrolling by timing, rather than
looking at the code.

The compiler is unrolling the code I provided, but then optimised quite badly.
As this might not be the fault of the loop optimiser, but some other piece of
code, I have opened a new bug report for it: 19078

Sorry for the inconvience.
