665d5e2a - [PyTorch][JIT] Audit interpreter for extra copies (#54029)

[PyTorch][JIT] Audit interpreter for extra copies (#54029) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/54029 I found what appear to be some missed moves and/or extra copies in the JIT interpreter. ghstack-source-id: 123958682 Test Plan: Existing CI for correctness Ran AdIndexer inline_cvr local_ro model benchmark with static_runtime off via `env bin=/tmp/ptvsc2_predictor_bench.StaticDispatchModeFile static_runtime=0 caffe2=0 scripts/swolchok/static_runtime/inline_cvr/run_local_ro.sh` before: ``` I0315 14:25:23.916893 3075680 PyTorchPredictorBenchLib.cpp:215] PyTorch run finished.
