Issue: taichi-dev#2906 ### Brief Summary When solving a sparse linear system without reordering the system matrix, `analyze_pattern` and `factorize` would consume a lot of GPU memory. For example, the `res` in the `stable fluid` example can not be larger than 500. After reordering the sparse system matrix, we can set `res=512` now.
