[TensorExpr] Use couldMoveBefore instead of couldMoveAfter checks in the fuser pass, add CPP tests. (#38592) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/38592 I'm not sure that using couldMoveAfter was incorrect, but using couldMoveBefore is more consistent with other subgraph-extraction passes (old fuser, create autodiff graphs, etc.), so it would make it easier to unify their implementations after this change.
