This is ugly, but I think it's necessary if we're going to do #26991.

The only limitation here is that you can't mutate BigInts from the system image, but I think that's acceptable since we don't expose a mutating API, constants shouldn't be mutated anyway, and we typically have more control over what goes into a system image (as opposed to a precompiled package).
