This **roughly** corresponds to Goal 3.2 in https://docs.google.com/document/d/1iiLNwR5ohAsw_ymfnOpDsyF6L9RTUaHMpD8YLw-jxEw/edit#
Namely:
It adds the following:
* SymbolicIntNode interface
* LazySymbolicIntNode implementation
* Lazy `narrow_copy` implementation
* Need add support for SymInt in codegen
* Test (below)
```cpp
TEST(LazyDynamicOpsTest, NarrowCopy) {
auto x = torch::rand({5, 10, 10}).to(kLazy);
const size_t Y_DIM = 3;
const size_t X_DIM_INDEX = 2;
auto y = torch::rand({Y_DIM}).to(kLazy);
auto ly = torch::lazy::TryGetLtcTensor(y);
auto dim_node = MakeNode<SizeNode>(ly->GetIrValue(), 0);
auto lmn = new torch::lazy::SymbolicIntNode(dim_node);
auto z = x.narrow_copy(X_DIM_INDEX, 0, lmn->toSymInt());
AllClose(z.cpu(), x.cpu().narrow_copy(X_DIM_INDEX, 0, Y_DIM));
}
```

(cherry picked from commit faec5043df56639e2fd23de2d91ae796e4f3df70)
Summary:
Tensor.is_alias_of relies on Storage to perform. However, LTCTensorImpl was
not implemented with that in mind. This commit adds a fake storage to LazyTensor
as a marker to mark LazyTensors that point to the same storage. The reason
why it's not done at LTCTensorImpl is that LazyTensor maintains the view ops/alias
logic in LazyTensor class instead of relying on TensorImpl to do the check.

Op diagonal is a view op which we can't code-gen yet. Therefore, support

(cherry picked from commit 84155528fce484627c9688cfd92fd4aeb68219e5)
Summary:
Previously, the torchscript backend would be (partially) initialized at startup.
- the dispatcher registrations would be registered,
- but other backend components would not be initialized until explicitly calling
the backend init function
With this change, the torchscript backend is not initialized until its explicit
initialization function is called.
This enables external backends to register their own backend instead of the torchscript
backend to the same (Lazy) key.

(cherry picked from commit 60945adbefb6a8d19f89e330f8b344d076b13bfc)
Summary:
Hooks into existing autograd codegen script (generate_code.py) to take advantage of its integrations into buck/cmake/bazel.
Adds a new option (--gen_lazy_ts_backend) to. generate_code.py, calling this from CMake OSS build and fbcode build, but not from other internal xplat/ovrsource builds (these could be opted in later)
Bazel support is added in a later diff.
Includes one generated file (torch/csrc/lazy/generated/LazyIr.h) in a unit test (test/cpp/lazy/test_ir.cpp) to partially verify the generator is working, but does not compile the remaining output sources from the generator yet as they depend on other files not yet landed from lazy_tensor_staging branch.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/72875
This diff contains changes from several PRs landed to lazy_tensor_staging branch.
* generating 'fallback' overrides for each codegenned op, useful for debugging
* supports operators which are missing aten:: symbols for op names, instead using their string counterpart
* makes the IR class a base class instead of hardcoding the assumption of TS
It also resolves lint issues and in particular cleans up the following:
* {Type}s shouldn't be passed into isValueType, and using the catch-all base class of CType is nicer than specifying a list of types.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/69277
LazyView is the main class for tracking alias caused by view
ops. The corresponding IR classes for view ops are hand-written now, and
we can switch to code-gen them in future. For certain view ops, they
have a reverse IR class to perform inplace update in the backward
direction on a chain of alias ops.
As part of the future work, we will simplify the logic for LazyView once
the functionalization pass in core is ready to use.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/68201
Hash(c10::Scalar) made a bad assumption that it was valid to just hash over all the bytes of data of the c10::Scalar struct.
Becuase c10::Scalar stores a union of different (float/int/complex) types with different sizes, not all bytes are valid in all cases. Hash() should only read the bytes corresponding to the currently active type.
Test Plan: Added new unit tests. Verified HashTest.Scalar failed with the original Hash() impl and then fixed.

This commit upstreams class BackendDevice to the master, which is a backend
specific representation of the actual hardware, for instances, CPU, GPU, or

both IR constructions and lowerings.
