This PR relaxes the conditions of Meta-Schedule schedule rule CrossThreadReduction. The rules are previously a bit over-strict, and some workloads with small reduction loop length are unable to be optimized by cross-thread reduction automatically. In this PR, we relax the rules so that such workloads can be optimized.
