Summary: Following up on D68471, this CL introduces some `getStats` APIs to gather statistics in char buffers (`ScopedString` really) instead of printing them out right away. Ultimately `printStats` will just output the buffer, but that allows us to potentially do some work on the intermediate buffer, and can be used for a `mallocz` type of functionality. This allows us to pretty much get rid of all the `Printf` calls around, but I am keeping the function in for debugging purposes. This changes the existing tests to use the new APIs when required. I will add new tests as suggested in D68471 in another CL.
