[InstCombine] Fold (A - B) u>=/u< A --> B u>/u<= A iff B != 0
https://rise4fun.com/Alive/KtL
This also shows that the fold added in D67412 / r372257
was too specific, and the new fold allows those test cases
to be handled more generically, therefore i delete now-dead code.
This is yet again motivated by
D67122 "[UBSan][clang][compiler-rt] Applying non-zero offset to nullptr is undefined behaviour"
