Hi Florian,

I do think this change is very important move in the right direction. Thanks for driving it. My main concern is essentially the same as for  D75981 <https://reviews.llvm.org/D75981>. I think such things should be done directly on CostModel. I've uploaded alternative implementation which does the same thing as this patch but in the CostModel. Please take a look and let me know if you like that or not. It would be really helpful to hear from others as well.
