I tried to run onnx-mlir bidaf-9.onnx But hit error in https://github.com/onnx/onnx-mlir/blob/main/src/Conversion/ONNXToKrnl/Math/Reduction.cpp#L709 because estimatedSimdLoopTripCount not initialized. Is this expected for Windows build of onnx-mlir?

Created a PR to create only one globalOp for all strings in a string literal https://github.com/onnx/onnx-mlir/pull/2727 This could save a lot of time when debugging [bidaf-9](https://github.com/onnx/models/blob/main/validated/text/machine_comprehension/bidirectional_attention_flow/model/bidaf-9.onnx) model.

The fix is in https://github.com/llvm/llvm-project/commit/c11627c2f4d550613a3cb360c89a0cf52d2eb720
