Move orphan instance/rule warnings to typechecker/desugarer.
Summary:
Instead of doing these warnings at MkIface time, we do them
when we create the instances/rules in the typechecker/desugarer.
Emitting warnings for auto-generated instances was a pain
(since the specialization monad doesn't have the capacity
to emit warnings) so instead I just deprecated -fwarn-auto-orphans.
Auto rule orphans are pretty harmless anyway: they don't cause
interface files to be eagerly loaded in.
