rework the ownership of subloop alias information: instead of keeping them around until the pass is destroyed, keep them around a) just when useful (not for outer loops) and b) destroy them right after we use them. This should reduce memory use and fixes potential bugs where a loop is deleted and another loop gets allocated to the same address. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112446 91177308-0d34-0410-b5e6-96231b3b80d8
