Thanks, I've moved it there.

I don't think it should be done this way for several reasons:
1. This info is actually needed by user when one uses `--ftime-trace` since 
json-file is usually dumped to random filename located in `/tmp/`. Therefore 
`--ftime-trace` means `--ftime-trace --verbose` itself. Without this info user 
cannot understand where dumped file is. How can he know about `--verbose`?
2. Option `--ftime-report` is much more chatty, it dumps several tables to 
terminal. This option just dumps to file, but tells where file is.
3. I have not found elegant way to check `--verbose` option here, one should 
add it to `clang::FrontendOptions` or so.

Ok, I've added more checks, parsing json file by python.
