It turned out that in the targeted case there is the following expression min(a,b) = min(min(a,c), b) where rhs min is reassociated. Due to this foldICmpWithMinMax can't handle it. I've uploaded a series of 3 patched for NaryReassociate  (https://reviews.llvm.org/D88285, https://reviews.llvm.org/D88286, https://reviews.llvm.org/D88287) which converts that to min(a,b) = min(min(a,b), c). With that in place foldICmpWithMinMax  does its job.

Abandoned.
