[TensorExpr fuser] Guard nodes that have tensor output properties determined by non-tensor inputs (#44137)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/44137
We only insert guards on Tensor types, so we rely on the output
of a node being uniquely determined by its input types.
bail if any non-Tensor input affects the output type
and cannot be reasoned about statically
