Objective-C XRef Helper.py

When deployment target on iOS 14+/tvOS 14+/watchOS 7+/macOS 11+, Objective-C runtime will use the relative method list to optimize memory usage. Learn WWDC 2020 - Advancements in the Objective-C runtime

However Hopper (v5.5.3) seems could not parse the selector and calls. So this scripts fix this and add the XRef between calls.

You can teach ld64 to force enable relative method list via -objc_relative_method_lists as well.
