Summary:
When renaming an Objective-C method `-foo` to `-bar` on an Objective-C type `Foo`, and a Swift typealias `SwiftFoo = Foo` exists, uses of `SwiftFoo.foo()` won’t be renamed to `SwiftFoo.bar()`.

Steps to Reproduce:
In a mixed Objective-C/Swift project with the following source:

```objc
@interface Foo
- (void)foo;
@end
@implementation Foo
@end
```

```swift
typealias SwiftFoo = Foo
SwiftFoo().foo()
```

Rename `- (void)foo;` to `- (void)bar;` using Xcode 9’s refactoring tools.

Expected Results:
`SwiftFoo().foo()` should be renamed to `SwiftFoo().bar()`.

Actual Results:
`SwiftFoo().foo()` is not modified at all.

Version:
Xcode 9 (9M189t)
