9ce83387 - [JIT] Introduce a fake Tensor creation node for IR unit tests (#33914)

[JIT] Introduce a fake Tensor creation node for IR unit tests (#33914) Summary: **Summary** There is often a need to create a Tensor when writing IR by hand for JIT optimisation pass unit tests. The only options for this today are real Tensor creation functions like `aten::ones`. Any test that uses these functions must also use the same default arguments as the Python/C++ API, which means that all of the tests have to be updated when the API is updated. This commit introduces a new primitive, `prim::MakeTestTensor` with schema `() -> Tensor` that should be used in unit tests instead of real Tensor creation functions. This new primitive has no public-facing API, so the maintenance burden is much lower. **Testing** This commit updates the alias analysis and DCE tests to use `prim::MakeTestTensor` instead of `aten::rand`, `aten::ones`, and `aten::zeros`. ``` $ ./bin/test_jit CUDA not available.
