Allow CrossThreadPersistent and its weak form to access ASAN poisoned memory from the GC entry points. In general, payloads of to-be-finalized objects are poisoned until the finalizer actually runs to avoid accidentally touching that payload. In the case of cross-thread handles, these may need to be cleared by a different thread before the finalizer actually runs. In order to clear those references, the slot needs to be unpoisoned. This is issue is ASAN-only and does not affect production or other debug builds.

C++ Garbage Collection
This directory provides an open-source garbage collection library for C++.
The library is under construction, meaning that all APIs in this directory are incomplete and considered unstable and should not be used.
