Chris Smowton 5b34c05916 UnreachableStatement: tolerate more harmless unreachable return statements 
The Golang compiler isn't particularly good at spotting paths that don't need a return statement due to a dominating noreturn statement (e.g. os.Exit(1)), so dead return statements are common. We already tried to tolerate some instances of this pattern; this additionally allows 'true' and 'false' literals, and anything of type 'error'.

The carte-blanche for error values aims to accommodate the pattern "abort(); return whateverErrorWouldOtherwiseBeAppropriate();", which is probably preferable to "return nil", a misleading no-error indication.
