Control-flow due to iterators is treated the same as any other.
The only exception is that plain 'for i=a,b,c' loops get special
treatment to avoid overflow checks for the control variable.

So create a benchmark from a real-world use case and measure the
performance. That might be hard though, since IMHO the whole thing
looks a lot like a solution in search of a problem ...
