Okay, I've implemented these APIs and converted a couple of passes to use them, please take a look and review. https://github.com/apache/incubator-tvm/pull/4886
@haichen @MarisaKirisame I'm noticing that the passes with these edge cases all seem to be doing more complicated things than the simple post-order DFS targeted here. I'm still looking at them, but I think that should be a second PR?
