For `AddressSanitizer` I think this might refer to the GlobalsMetaData and ShadowMapping made during initialization, but I think they get reset on each function run. All tests with the legacy PM still seem to pass though which I think indicates that the logic is still sound even with the ASan functionality separated from the legacy pass.
