Yes. I've just added an assert and executed hs-tier1-3 and all hotspot tests with -Xcomp. The assert
only triggered with my TestOneIterationStripMined.java. Therefore, an alternative solution would be
to just bail out of split-if when the region is a CountedLoop because the current implementation
does not support CountedLoops anyway.

What do you think?

Thanks,
