Bjorn Pettersson b37f5f2114 Inform pass manager when child loops are deleted ... As part of the nontrivial unswitching we could end up removing child loops. This patch add a notification to the pass manager when that happens (using the markLoopAsDeleted callback). Without this there could be stale LoopAccessAnalysis results cached in the analysis manager. Those analysis results are cached based on a Loop* as key. Since the BumpPtrAllocator used to allocate Loop objects could be resetted between different runs of for example the loop-distribute pass (running on different functions), a new Loop object could be created using the same Loop pointer. And then when requiring the LoopAccessAnalysis for the loop we got the stale (corrupt) result from the destroyed loop.
