  Log Message:
  -----------
  [mlir][Arith] ValueBoundsInterface: speedup arith.select (#113531)

When calculating value bounds in the arith.select op , the compare
function is invoked to compare trueValue and falseValue. This function
rebuilds constraints, resulting in repeated computations of value
bounds.

In large-scale programs, this redundancy significantly impacts
compilation time.
