[Pytorch Mobile] Only preserve bundled input helpers for forward if they exist (#51884) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/51884 it is now possible to bundle inputs and not bundle them for forward. This is ok and so we need to account for that. ghstack-source-id: 121266667 Test Plan: Manually bundle inputs for a function not named forward. Call optimize_for_mobile and make sure the functions are still there. {P173289878} Reviewed By: iseeyuan Differential Revision: D26304558 fbshipit-source-id: 79f82d9de59c70b76f34e01f3d691107bf40e7bc
