Inheritance on self doesn't work right in default methods

[catamorphism]

This should work:

trait Positioned {
  fn SetX(int);
}

trait Movable: Positioned {
  fn translate(dx: int) {
    self.SetX(self.X() + dx);
  }
}

It fails to typecheck:

src/test/run-pass/issue-2616.rs:13:4: 13:13 error: attempted access of field `SetX` on type `self`,
but no field or method with that name was found
/Users/tchevalier/rust2/src/test/run-pass/issue-2616.rs:13     self.SetX(self.X() + dx);

I've almost fixed this -- I just ran into another incomplete bit of code in trans that I want to fix too.

@catamorphism : there's a test for this, issue-3979-generics.rs. It had bit-rotted a bit, but after replacing impl Ty : Tr with impl Tr for Ty, I'm now getting an ICE. Should I re-open this bug, or is this an unrelated bug?

[catamorphism]

@jbclements Reopen or open a new bug if you're not sure it's the same ICE, either way :-)

Decisions, darn it, I want decisions! :)

Ah well.

Well, I didn't see the error, and recreating it would require effort ;-)

(so I don't know whether or not it's the same error)
