[Discussion] Supporting 0-dim Buffer

[junrushao]

0-dimensional buffers are ubiquitous in real-world scientific computing. However, in our TensorIR implementation, it is possible that we missed out checking those corner cases.

I would love to devote this thread to gather ideas on what potential improvements we should do, and possibly get someone (Tristan, Xiyou, Wuwei or anyone) fixing those issues
