LLDB evaluates some utility expression to update the Objective-C class list that ends up calling function such as `free` or `objc_copyRealizedClassList_nolock`. This adds a test that just tries to define our own bogus version of `objc_copyRealizedClassList_nolock`. It just tests that LLDB doesn't crash as we currently don't have a way to tell LLDB to look for the function in a specific library.
