[NFCI-ish][SimplifyCFG] FoldBranchToCommonDest(): really don't deal with uncond branches

While we already ignore uncond branches, we could still potentially
end up with a conditional branches with identical destinations
due to the visitation order, or because we were called as an utility.
But if we have such a disguised uncond branch,
we still probably shouldn't deal with it here.
