[DO NOT LAND] Test run for MLP bias accuracy issue

[xuzhao9]

torch.compile has numeric issue with used with torch.amp.autocast and bias

The problem is gone when:

1. Not using amp, or
2. Not using bias

#607

Reproduce:

LD_LIBRARY_PATH="$HOME/.conda/envs/py312/lib" python run.py --op mlp  --metrics accuracy --use_bias --num-inputs 1

The issue is not related to amp. It is only related to the post_grad pass of pt2 where it decomposes addmm into mm + triton add. This should be easily reproduced with a simpler test.
