Emit trait method bodies in statics
And use this as the target of the default methods or
statically resolved super or $init calls.
The call-site change is predicated on `-Yuse-trait-statics`
as a stepping stone for experimentation / bootstrapping.
I have performed this transformation in the backend,
rather than trying to reflect this in the view from
Scala symbols + ASTs.
We also need to add an restriction related to invokespecial to Java
parents: to support a super call to one of these to implement a
super accessor, the interface must be listed as a direct parent
of the class.
The static method names has a trailing $ added to avoid duplicate
name and signature errors in classfiles.
