I have posted a patch(https://reviews.llvm.org/D77319) to remove the getNegatibleCost. It is almost ready now. I am not sure if it is the best way , and welcome for the comments in advance. Regarding to the opportunities for this patch, can you double confirm it together with my patch to see if there is any improvement ?
