Artem Dergachev f2192b204f [analyzer] RetainCount: A function isn't a CFRetain if it takes no arguments. ...

Don't crash when a function has a name that starts with "CF" and ends with
"Retain" but takes 0 arguments. In particular, don't try to treat it as if
it returns its first argument.

These problems are inevitable because the checker is naming-convention-based,
but at least we shouldn't crash.
