  Log Message:
  -----------
  [mlir][Linalg] Add canonicalization of linalg op -> dim op.

Add canonicalization to replace use of the result of a linalg
operation on tensors in a dim operation, to use one of the operands of
the linalg operations instead. This allows the linalg op itself to be
deleted when all its non-dim uses are removed (say through tiling, etc.)

  Log Message:
  -----------
  [mlir][Linalg] NFC: Verify tiling on linalg.generic operation on tensors.

With the recent changes to linalg on tensor semantics, the tiling
operations works out-of-the-box for generic operations. Add a test to
verify that and some minor refactoring.
