[llvm] [LoopInterchange] Prevent interchange if one index is constant and the other has loop carried dependence (PR #79123)

This doesn't look like the correct approach to me. A constant index should result in a scalar dependence, so there is no need to specify an output parameter to the `depends` interface.
