Qualifier of synthetic select `applyDynamicNamed` should have an opaque position

[scabug]

The kind of position assigned to the qualifier d in the below example is incorrect, and this result in incorrect hyperlinking and semantic highlighting in the Scala IDE

object X {
      val d = new D
      d(10) // <-- hyperlinking on `d` should jump to the declaration just above
    }

import language.dynamics
class D extends Dynamic {
  def applyDynamic(name: String)(value: Any) = ???
}

Hyperlinking on d should resolve to the declaration of d, not the applyDynamic method in class D.
