It now includes /ffi_test_functions_generated.cc and prints instructions on how to use the generated bundle. This CL adds some TODOs and deletes the non-migrated copy that was in the NNBD folder. Finally, this CL disable a check that fails because of static linking on iOS. Issue https://github.com/dart-lang/sdk/issues/39570.
