Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/26851 Add codegen option to remove backward ops from jit-op-registry as they are not likely to be used for inference only mobile build. Measured ARM-v7 AAR build size change: 5,804,182 -> 5,331,219. Test Plan: - build and integrate with demo app; Differential Revision: D17587422 Pulled By: ljk53 fbshipit-source-id: 08c0fc7a710698a0d4baaf16bbb73cb812b1126a
