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.

We shouldn't rely on the literal value given in the `literals` table, but use the exact value (where available) instead.

Remove Entity.getAUse() and replace uses with getAReference().

The former had result type `Ident`, so it wouldn't pick up references to methods and fields. Apart from that, it is subsumed by the latter anyway.
