[CodeCompletion] Eliminate CodeCompletionCallbacks::completeExpr() Well, this does nothing. It just set the parser position twice and calls the consumer's 'handleResults()' without any reason. It seems it was intended to be a "fallback" completion, but it was never implemented properly. So just remove it for now. rdar://problem/58102910
