[ObjC] Method implementations should have some way to see potential callers

What is the feature you'd like to have?
Objective-C method implementations should have some way to show potential callers (via objc_msgSend or similar). This might be as simple as adding cross-references.

When using "Resolve Dynamic Dispatch Calls" the method implementation naturally has cross-references to any callers that were rewritten to it.

Are any alternative solutions acceptable?
The current workaround to see potential callers of a method implementation is to use cross-references to navigate from the implementation to its selector, then select the selector in the linear / graph view. That will show the selector's cross references which will include all objc_msgSend / objc_msgSendSuper2 callers that reference it.

Additional Information:
"Resolve Dynamic Dispatch Calls" is no longer on by default. It was disabled because it always resolves selectors to the first class that happens to implement the selector. This is often entirely wrong for common selector names.
