Mikhail Zolotukhin e975169426 [TensorExpr] Redesign Tensor class. (#50995) ... Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/50995 This change makes 'Tensor' a thin wrapper over 'Buf' and 'Stmt', and merges it with recently introduced 'CompoundTensor'. A statement for the tensor is either passed directly to the Tensor constructor (akin to 'CompoundTensor'), or is built immediately in constructor. LoopNest is no longer responsible for constructing statements from tensors - it simply stitches already constructed statements contained in Tensors. This has a side effect that now we cannot construct several loopnests from the same tensors - we need to explicitly clone statements if we want to do that. A special copy constructor was added to LoopNest to make it more convenient (note: this only affects tests, we don't usually create multiple loopnests in other places).
