  Log Message:
  [mlir][memref] Extend multi-buffering transform

Extend multi-buffering to simplify the affine map created if any of its operands are constants. This avoids downstream problems where more complex affine.apply operations cannot be expanded.
Transfer attributes from the old allocation to the new allocation.
