[ConstantFold] Remove another incorrect icmp of GEP fold
This fold is not correct, because indices might evaluate to zero
even if they are not a literal zero integer. Additionally, this
fold would be wrong (in the general case) for non-i8 types as well,
due to index overflow.
Drop this fold and instead let the target-dependent constant
folder compute the actual offset and fold the comparison based
on that.
