a6f953156e [StaticRuntime] Add TensorExpr fusion with dynamic shapes in SR (#69475)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/69475

This diff adds TensorExpr fusion with dynamic shapes in SR. This includes tracing the input graph with sample inputs, and then performing fusion with generalization to get fused graphs with dynamic shapes.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/50217

If we fuse small groups, things are slow

f4226b5c90 [static runtime] add static subgraph fusion pass (#49185)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49185

This diff adds a fusion feature that will let us use static runtime for *parts* of the graph.  This will prove useful in cases where fully eliminating control flow is hard etc.

TODO:
[x] factor out into separate fusion file
[x] add python test case
[x] add graph that isn't fully lowered test case
[x] add graph that has weird list/tuple outputs test case

the loop example looks quite good:
```
graph(%a.1 : Tensor,
      %b.1 : Tensor,
      %iters.1 : int):
  %12 : bool = prim::Constant[value=1]() # /data/users/bwasti/fbsource/fbcode/buck-out/dev/gen/caffe2/test/static_runtime#binary,link-tree/test_static_runtime.py:110:4
  %c.2 : Tensor = prim::StaticSubgraph_0(%a.1, %b.1)
  %c : Tensor = prim::Loop(%iters.1, %12, %c.2) # /data/users/bwasti/fbsource/fbcode/buck-out/dev/gen/caffe2/test/static_runtime#binary,link-tree/test_static_runtime.py:110:4
    block0(%i : int, %c.12 : Tensor):
      %c.10 : Tensor = prim::StaticSubgraph_1(%a.1, %c.12, %b.1)
      -> (%12, %c.10)
  return (%c)
with prim::StaticSubgraph_0 = graph(%0 : Tensor,
      %4 : Tensor):
  %5 : int = prim::Constant[value=2]()
  %6 : Tensor = aten::mul(%4, %5) # /data/users/bwasti/fbsource/fbcode/buck-out/dev/gen/caffe2/test/static_runtime#binary,link-tree/test_static_runtime.py:109:12
  %2 : int = prim::Constant[value=1]()
  %c.2 : Tensor = aten::add(%0, %6, %2) # /data/users/bwasti/fbsource/fbcode/buck-out/dev/gen/caffe2/test/static_runtime#binary,link-tree/test_static_runtime.py:109:8
  return (%c.2)
with prim::StaticSubgraph_1 = graph(%1 : Tensor,
      %7 : Tensor,
      %8 : Tensor):
  %9 : int = prim::Constant[value=1]()
  %c.4 : Tensor = aten::add(%7, %8, %9) # /data/users/bwasti/fbsource/fbcode/buck-out/dev/gen/caffe2/test/static_runtime#binary,link-tree/test_static_runtime.py:111:12
  %5 : int = prim::Constant[value=2]()
  %c.7 : Tensor = aten::mul_(%c.4, %5) # /data/users/bwasti/fbsource/fbcode/buck-out/dev/gen/caffe2/test/static_runtime#binary,link-tree/test_static_runtime.py:112:8
  %2 : int = prim::Constant[value=1]()
  %c.10 : Tensor = aten::sub_(%c.7, %1, %2) # /data/users/bwasti/fbsource/fbcode/buck-out/dev/gen/caffe2/test/static_runtime#binary,link-tree/test_static_runtime.py:113:8
  return (%c.10)
```

(Note: this ignores all push blocking failures!)
