and has a new API so hopefully we can use both side-by-side as we
migrate.

I'd maybe rather name the folder "softfloat3" instead of "softfloat3c"
... otherwise it does not match anymore if we ever want to update to
version 3d (which is likely just a minor release with some few bug
fixes, so we likely don't want to maintain that in a separate folder)
