Add all members to be mixed in into a (non-trait-) class These are: for every mixin trait T that is not also inherited by the superclass: add late interface members to T and then:
- if a member M of T is forwarded to the implementation class, add a forwarder for M unless one exists already. The alias of the forwarder is the static member it forwards to.
- for every abstract accessor in T, add a field and an implementation for that accessor
- for every super accessor in T, add an implementation of that accessor
- for every module in T, add a module

- def publicizeTraitMethod(sym: Global.Symbol): Unit
Some trait methods need to be implemented in subclasses, so they cannot be private.
Some trait methods need to be implemented in subclasses, so they cannot be private.
We used to publicize during explicitouter (for some reason), so the condition is a bit more involved now it's done here (need to exclude lambdaLIFTED methods, as they do not exist during explicitouter and thus did not need to be excluded...)
They may be protected, now that traits are compiled 1:1 to interfaces. The same disclaimers about mapping Scala's notion of visibility to Java's apply: we cannot emit PROTECTED methods in interfaces on the JVM, but knowing that these trait methods are protected means we won't emit static forwarders.
JVMS: "Methods of interfaces may have any of the flags in Table 4.6-A set except ACC_PROTECTED, ACC_FINAL, ACC_SYNCHRONIZED, and ACC_NATIVE (JLS §9.4)."
TODO: can we just set the right flags from the start?? could we use the final flag to indicate a private method is really-really-private?
