  -----------
  [mlir][Linalg] Avoid generating illegal operations during elementwise fusion.

In some cases, fusion can produce illegal operations if after fusion
the range of some of the loops cannot be computed from shapes of its
operands. Check for this case and abort the fusion if this happens.
