[cfe-users] Compile from source code string

If it's possible, then of course LibClang as it's backward compatible, but
I know that it's restricted in functionality, so if LibClang don't give
such freedom, then LibTooling.

Thanks for the advice! This should work on unix, but what's about other

Linux, Macos and Windows, and with code solution it'll be no different to
support all of them as well as it'll be bit more secure, I think.
