Florian Diebold e5fd550dfd Use correct, full substs for self type in impl
Without arbitrary self types, the self type could never refer to the method type
parameters, so this wasn't a problem; but with arbitrary self types, it can.

This fixes the crash from #6668; but it doesn't make method resolution work for
these methods.
