[LoopInterchange] Handle confused dependence correctly (#140709) ...

This patch fixes the handling of a confused `Dependence` object. Such an
object doesn’t contain any information about dependencies, so we must
process it conservatively. However, it was converted into a direction
vector like `[I I ... I]`. As a result, it was treated as if there are
no loop-carried dependencies, which can lead to illegal loop exchanges.

Fixes #140238
