Tung D. Le 2b5d1776ff [MLIR][Affine-loop-fusion] Fix a bug in affine-loop-fusion pass when there are non-affine operations 
When there is a mix of affine load/store and non-affine operations (e.g. std.load, std.store),
affine-loop-fusion ignores the present of non-affine ops, thus changing the program semantics.

E.g. we have a program of three affine loops operating on the same memref in which one of them uses std.load and std.store, as follows.
```
affine.for
  affine.store %1
affine.for
  std.load %1
  std.store %1
affine.for
  affine.load %1
  affine.store %1
```
affine-loop-fusion will produce the following result which changed the program semantics:
```
affine.for
  std.load %1
  std.store %1
affine.for
  affine.store %1
  affine.load %1
  affine.store %1
```

This patch is to fix the above problem by checking non-affine users of the memref that are between the source and destination nodes of interest.
