How much of opurtunities we miss this way? Perhaps we can simply merge
the blocks conservativly (ie remove the clobbers and keep uses)
I didn't measure, but I doubt it misses very many. After all, each
such "miss" would have caused this bug and it didn't occur in very many places.
I don't think it's worth the complexity.
