Hi!

I notice that IWYU is quite noisy when the code has correct includes:

```
(foo.h has correct #includes/fwd-decls)

(foo.cpp has correct #includes/fwd-decls)
```

This clutters our build logs and makes it harder to spot real issues. Is it possible to silence this somehow, so it only prints output on error? We are using `--verbose=3` to be able to see the explanation of why an include is needed (which line in code).

Looks like a duplicate of #999.
