  This phase performs the following functions, each of which could be split out in a mini-phase:

  This phase performs the following functions, each of which could be split out in a mini-phase:

  (1) Adds super accessors for all super calls that either appear in a trait or have as a target a member of some outer class.

  (2) Converts references to parameter fields that have the same name as a corresponding public parameter field in a superclass to a reference to the superclass field (corresponding = super class field is initialized with subclass field). This info is pre-computed by the `alias` field in Typer. `dotc` follows a different route; it computes everything in SuperAccessors and changes the subclass field to a forwarder instead of manipulating references. This is more modular.

  (3) Adds protected accessors if the access to the protected member happens in a class which is not a subclass of the member's owner.

  (4) Mangles the names of class-members which are private up to an enclosing non-package class, in order to avoid overriding conflicts. This is a dubious, and it would be better to deprecate class-qualified privates.

  (5) This phase also sets SPECIALIZED flag on type parameters with `@specialized` annotation. We put this logic here because the flag must be set before pickling.

  It also checks that:

  (1) Symbols accessed from super are not abstract, or are overridden by an abstract override.

  (2) If a symbol accessed accessed from super is defined in a real class (not a trait), there are no abstract members which override this member in Java's rules (see scala/bug#4989; such an access would lead to illegal bytecode)

  (3) Super calls do not go to some synthetic members of Any (see isDisallowed)

  (4) Super calls do not go to synthetic field accessors

  (5) A class and its companion object do not both define a class or module with the same name.

  TODO: Rename phase to "Accessors" because it handles more than just super accessors
