Add an "addUsedAAAnalyses" helper function Summary: Passes that call `getAnalysisIfAvailable<T>` also need to call `addUsedIfAvailable<T>` in `getAnalysisUsage` to indicate to the legacy pass manager that it uses `T`. This contract was being violated by passes that used `createLegacyPMAAResults`. This change fixes this by exposing a helper in AliasAnalysis.h, `addUsedAAAnalyses`, that is complementary to createLegacyPMAAResults and does the right thing when called from `getAnalysisUsage`.
