  Log Message:
  -----------
  [mlir][Linalg] Add canonicalization to remove no-op linalg operations.

linalg.generic/indexed_generic operations on tensors whose body is
just yielding the (non-induction variable) arguments of the operation
can be canonicalized by replacing uses of the result with the
corresponding arguments.
