  Log Message:
  -----------
  [mlir][linalg] Fold duplicate and unused inputs in linalg.generic

If an input bbArg is not used, its corresponding input operand is removed. If there are duplicate input operands or input operands that are also used as output operands, the duplicate input operands are removed. Output operands are never modified.
