  [MLIR][Linalg] Allow fusion of more than 2 linalg ops.

LinalgDependenceGraph was not updated after successful producer-consumer
fusion for linalg ops. In this patch it is fixed by reconstructing
LinalgDependenceGraph on every iteration. This is very ineffective and
should be improved by updating LDGraph only when it is necessary.
