Description

go-fuzz found a few math/big and go/constant bugs indirectly, via go/types and cmd/compile:

https://github.com/golang/go/issues/20227 https://github.com/golang/go/issues/20228

That's a pretty inefficient way to find them, though. We should run it on them directly and flush out a few more.
