6b8d20c0 - [pytorch][te] Don't start TE fusion groups with an unknown-typed result (#47884)

[pytorch][te] Don't start TE fusion groups with an unknown-typed result (#47884) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/47884 We need to know output types of everything in a fusion group to ensure that we generate correctly-typed tensors. We were incorrectly starting a fusion group with an unknown-typed output. Test Plan: New unit tests: ``` buck test //caffe2/test:jit //caffe2/test/cpp/tensorexpr:tensorexpr ``` Reviewed By: eellison Differential Revision: D24932786 fbshipit-source-id: 83978a951f32c1207bbc3555a7d3bd94fe4e70fb
