Nikita Popov e3cec17b2d [InstSimplify] Remove incorrect icmp of gep fold (PR52429) 
As described in https://bugs.llvm.org/show_bug.cgi?id=52429 this
fold is incorrect, because inbounds only guarantees that the
pointers don't wrap in the unsigned space: It is possible that
the sign boundary is crossed by an object.

I'm dropping the fold entirely rather than adjusting it, because
computePointerICmp() fully subsumes it (just with correct predicate
handling).
