[mlir][linalg] LinalgOp-anchored empty tensor elimination
This revision adds a pre-bufferization transform that can reduce the number of allocation. It is similar to `bufferization.eliminate_empty_tensors`, but specific to LinalgOp.
The transform looks for `tensor.empty` ops where the SSA use-def chain ends in an "ins" operand of a `LinalgOp`. If the same `LinalgOp` has an unused "outs" operand (and some other conditions are met), this "outs" operand can be used instead of the `tensor.empty` and the "ins" operand can be turned into an "outs" operand.
