This phase adds outer accessors to classes and traits that need them. Compared to Scala 2.x, it tries to minimize the set of classes that take outer accessors by scanning class implementations for outer references.
The following things are delayed until erasure and are performed by class OuterOps:
- add outer parameters to constructors
- pass outer arguments in constructor calls
replacement of outer this by outer paths is done in Erasure. needs to run after pattern matcher as it can add outer checks and force creation of $outer

Denotations with a symbol where infoMayChange
is false are guaranteed to be unaffected by this transform, so transformInfo
need not be run. This can save time, and more importantly, can help avoid forcing symbol completers.

First, add outer accessors if a class does not have them yet and it references an outer this. If the class has outer accessors, implement them. Furthermore, if a parent trait might have an outer accessor, provide an implementation for the outer accessor by computing the parent's outer from the parent type prefix. If the trait ends up not having an outer accessor after all, the implementation is redundant, but does not harm. The same logic is not done for non-trait parent classes because for them the outer pointer is passed in the super constructor, which will be implemented later in a separate phase which needs to run after erasure. However, we make sure here that the super class constructor is indeed a New, and not just a type.

Is this phase the standard typerphase? True for TyperPhase, but not for other first phases (such as FromTasty or Parser). The predicate is tested in some places that perform checks and corrections. It's different from ctx.isAfterTyper (and cheaper to test).
