Fix thinko. If we follow a conditional branch, we should _not_
also try to rewrite the target, since we're now not even going
to reach that instruction.
More importantly, rewriting the first conditional branch will
have removed the parent to the second one, so then checking for
"single parent" will _not_ mean that we were it. Quite the reverse.
