Doug Gregor 8b80681394 Escalate the warning about the "== Self" type soundness hole to an error. ...

Swift 3 had a type soundness hole in protocol conformance checking
where the requirement contained an "== Self" constraint and the
witness was a member of a non-final class. We previously closed the
type soundness hole in PR #9830, but left it as a warning in Swift 3
compatibility mode.

Escalate that warning to an error. The optimizers break due to this
type soundness hole, and of course it can lead to other runtime
breakage because it violates the type system.

Fixes rdar://problem/28601761.
