[LLVMdev] ScalarEvolution, HowManyLessThans question for step > 1

I have a question about some code in ScalarEvolution.cpp, in the function
HowManyLessThans. Specifically, this function returns CouldNotCompute if
the iteration step is greater than one even when the NoWrap flags are set

// Test whether a positive iteration can step
