[SimpleLoopUnswitch] Ignore inner loops when injecting invariant conditions. PR60736

The transform and all related updates don't expect the situation when candidate
is from an inner loop. I think we *might* still do something in this case, but
the current implementation doesn't expect this and does incorrect loop info
updates in this situation.
