There is an error from auto schedular test. Not sure if it is related or flaky |

It seems very unlikely that these changes would cause that error. I'll try to rebuild. It looks like it passes locally as well. |

hey @comaniac @merrymercy can you check if the error from evolutionary search test https://ci.tlcpack.ai/blue/organizations/jenkins/tvm/detail/PR-6681/1/pipeline/ can be flaky? |

@masahi It seems to be an internal bug of the auto-scheduler rather than a flaky test. |

This PR contains two otherwise unrelated bug fixes / improvements that allow us to import a class of segmentation models using the Onnx frontend.
The first is the ability to broadcast the batch dimension of the left hand side argument of
batch_matmulto to the right hand side argument, where we previously only allowed rhs to lhs broadcasting. There are a few bug fixes in relay to enable this.The second is a fix to our strided slice shape inference to allow reverse slicing, specifically when the end is a negative number, indicating that we should iterate all the way to the first element. A test case in relay is added to catch this in the future.
Finally, I removed some unneeded type inference and shape checking in padding.
