[LICM] Allow AliasSetMap to contain top-level loops. When an outer loop gets deleted by a different pass, before LICM visits it, we cannot clean up its sub-loops in AliasSetMap, because at the point we receive the deleteAnalysisLoop callback for the outer loop, the loop object is already invalid and we cannot access its sub-loops any longer.
