RFR: JDK-8164094: javadoc allows to create a @link to a non-existent method [v2]

[Hannes Wallnöfer]

> Please review a simple fix in `JavacTrees` to only look up member references in the enclosing type if the reference does not contain an explicit type name. For example, `@see #method()` in a a doc comment of class `Outer.Inner` should find method `Outer.method()`, but `@see Inner#method()` should not (regardless of comment location).
