Very good stuff. This is great! Now we can add a boatload of tests to
make sure we don't disable optimizations by mistake. Hmm, I wonder what
form would false positives take. Say, we are expecting an expression to
disappear, but it turns out that it's code-motioned somewhere else where
it makes better sense... anyway, I'm rambling. We'll figure it out when
we get there.
For the time being, we could start adding lots of simple tests. Dan
Nicolaescu had a few tests for DCE and CCP that we could now add.
