Michael Lippautz e0c1a349ea cppgc: Properly clear (Weak)Peristent and WeakMember pointers 
The CL addresses two issues with (Weak)Persistent and WeakMember:
1. (Weak)Persistent pointers are cleared on heap teardown. Before this
   CL the pointers would contain stale values which could lead to UAF.
2. WeakPersistent and WeakMember are cleared using a combination of
   internal clearing methods and mutable fields which avoids the use
   of const_cast<>.

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.
