Reducing hello-world size

[NullVoxPopuli]

I think most further reductions will require declaring sideEffects.
But in the PR after this one, I'm going to try to make the sideEffects we know about more centralized to where they are used (if I can find them)

We still have 13Kb (brotli) we can get rid of
