  "message": "[MLIR][Presburger] optimize bound computation by pruning orthogonal constraints (#164199)\n\nIntegerRelation uses Fourier-Motzkin elimination and Gaussian\nelimination to simplify constraints. These methods may repeatedly\nperform calculations and elimination on irrelevant variables.\nPreemptively eliminating irrelevant variables and their associated\nconstraints can speed up up the calculation process.",
