Pooling.cpp changes causes windows builds to fail downstream in iree-org/iree

[renxida]

Recent changes causes windows (and only windows) builds to fail downstream in iree. See logs at: https://github.com/iree-org/iree/actions/runs/13757267783/job/38466645214#step:14:10632

I think it has something to do with

• Extend to 1D and 3D the torch to linalg lowering of the average pool operator with count_include_pad = false #4035

Why I think this is caused by a torch-mlir change

I am specifically seeing these errors:

D:\a\iree\iree\c\third_party\torch-mlir\lib\Conversion\TorchToLinalg\Pooling.cpp(1098): error C2131: expression did not evaluate to a constant
D:\a\iree\iree\c\third_party\torch-mlir\lib\Conversion\TorchToLinalg\Pooling.cpp(1099): error C2039: 'getDivisorOverride': is not a member of 'mlir::torch::Torch::AtenAvgPool1dOp'

Windows builds were succeeding up to 0307 but failed for 0308, 0309, 0310.

Timeframe lines up with a recent torch-mlir bump in iree.

Why I think this is caused by #4035

The error message mentions Pooling.cpp in TorchToLinalg

I have a fix, will push a PR shortly. Not yet sure why the new CI missed this though.

Fix is up for review at #4086.

I can repro this in my local (downstream) IREE build. I can't repro this on the same system yet in torch-mlir standalone. Checking how the compiler flags differ between projects.
