[BMG] test_torchinductor_opinfo native_batch_norm float16 comprehensive tests fail on BMG (pass on PVC) in torch-2.14

[daisyden]

Summary

BMG-specific Inductor OpInfo failures observed with torch-2.14. These cases pass on PVC but fail on BMG, so they are hardware (BMG) specific.

Affected cases

• inductor/test_torchinductor_opinfo.py::TestInductorOpInfoXPU::test_comprehensive__native_batch_norm_legit_xpu_float16
• inductor/test_torchinductor_opinfo.py::TestInductorOpInfoXPU::test_comprehensive_native_batch_norm_xpu_float16

Environment

• Torch: 2.14
• Hardware: Intel BMG (fails)
• Reference: Intel PVC (passes)
• dtype: float16

Reproduction

python test/inductor/test_torchinductor_opinfo.py TestInductorOpInfoXPU.test_comprehensive__native_batch_norm_legit_xpu_float16
python test/inductor/test_torchinductor_opinfo.py TestInductorOpInfoXPU.test_comprehensive_native_batch_norm_xpu_float16

Notes

• BMG-only regression: both cases pass on PVC with the same torch-2.14 build.
