Emit text in pass reduction when in text mode (#2792)

Without this we emitted a binary, which confused the size comparisons.

(When reducing a smaller size is usually a good sign. And also it provides
a deterministic way to know when to stop - we can't infinite loop if we keep
going while the size shrinks.)
