99a10c37 - [PyTorch][Static Runtime] Fix dtype changing between iterations for to() (#67394)

[PyTorch][Static Runtime] Fix dtype changing between iterations for to() (#67394) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/67394 ghstack-source-id: 146464294 Test Plan: Added new test, which failed but now passes. Checked perf on ctr_mobile_feed local net (still not on recordio inputs yet), looks neutral ``` Stable, local ======================================== I1027 13:40:23.411118 2156917 PyTorchPredictorBenchLib.cpp:131] PyTorch predictor: number of prediction threads 1 I1027 13:40:48.708222 2156917 PyTorchPredictorBenchLib.cpp:249] PyTorch run finished.
