I think the issue is that the loop nest analysis is a loop analysis. If we already have the loop nest analysis cached, if there's an inner loop that gets modified (deleted in this case), the loop nest analysis on the outer-most loop is not invalidated. Perhaps the loop nest shouldn't be a loop analysis.
