GetWriteBarrierType used to consider the slot so that a barrier is not triggered for on-stack slots. For strongifying weak collections we want the write barrier to trigger even if the backing store is only reachable from stack.

Oilpan: C++ Garbage Collection
Oilpan is an open-source garbage collection library for C++ that can be used stand-alone or in collaboration with V8's JavaScript garbage collector.
Key properties
- Trace-based garbage collection;
- Precise on-heap memory layout;
- Conservative on-stack memory layout;
- Allows for collection with and without considering stack;
- Incremental and concurrent marking;
- Incremental and concurrent sweeping;
- Non-incremental and non-concurrent compaction for selected spaces;
See the Hello World example on how to get started using Oilpan to manage C++ code.
Oilpan follows V8's project organization, see e.g. on how we accept contributions and provide a stable API.
