To see the payoff, look at test/dynamo/test_logging.py
The general idea is to refactor produce_guards into produce_guards_verbose which also returns verbose code parts, which have our annotations.
The rest of the logic is plumbing around SLocs to the places they need to be so we can print them. Guards are easy; value ranges and duck sizing take more care.

When tensor folding occurs during matmul operation returned tensor is a view. This can cause issues when matmul is used inside a custom function and such view is then returned as output. Then it cannot be modified inplace and causes errors.
It can be especially problematic when after such function inplace allreduce is performed.
Issue is resolved when unsafe_view is returned from matmul instead. This solution aligns matmul decomposition with eager implementation in such a way that a non view tensor is returned.
Test included in this PR reproduces the issue.

In preparation for tracing through DeviceContext (defb515306/torch/utils/_device.py (L66))
This PR adds support for calling the setattr of thread local objects. These objects have a slots impl, and since this doesn't appear to have any side effects, we call this setattr impl when replaying mutations, since calling `object.__setattr__` on these objects results in a type error.

Fixes https://github.com/pytorch/pytorch/issues/133858
Details: Previously Dynamo would treat dataclasses as UserDefinedVariables. This was non-desirable if we would like to proxy the value into the graph, which is needed for TensorSubclassMetadata. To rectify this, frozen dataclasses are now able to be proxied similarly to NamedTuples. We require the object to be frozen, because if arbitrary mutation were allowed, we would need to replay those mutations in the graph after construction of the object.
For tracing construction of the variable, the generated `__init__` for the dataclass uses `object.__setattr__` because frozen dataclasses throw errors on the usual `__setattr__` invocation. With this treatment, no special handling is needed in dynamo for frozen dataclass construction.

In the regular Tensor case, when you call Tensor.data, there's a check
for if inference mode is active. If it is active, then we don't set the
version counter. We replicate this check for Tensor Subclasses (the bug
was we were trying to set the version counter on a FakeTensor in
inference_mode).

We promise the user that these custom ops (and their kernels) are black
boxes w.r.t. torch.compile. Unfortunately Dynamo can turn itself back
on in the implementation of the custom operator, so we force it off by
disabling Dynamo

Fixes#132290
This PR attempts a more invasive / complete solution than the one from #132338, which removes immediate tensor fields from the `tensor_dict` copy stored in node meta. The approach taken here is to store only those fields of the `tensor_dict` which are absolutely utilized somewhere else.
So far, this appears to be limited to:
* `_dynamo_static_input_type`
* `tag` (at least in the tests). Discussion at #94080 appears to indicate this is depended on for export
(CI may point out more)

This breaks the inference we made that if you cat an N-D tensor with a 1-D tensor of size (u0,), the u0 must be zero, but no one really wanted that anyway...
