'private' top-level operators are OK for 'fileprivate' conformances
This part of the code /isn't/ using access scopes yet, and probably
should be switched to that soon, but for now, just allow top-level
operators marked 'private' to satisfy a conformance for a type or
protocol marked 'fileprivate'.
More progress on SE-0025 ('private' and 'fileprivate')
