Description
Loom added the first IN_NATIVE oop store to C2 code, when switching the current virtual thread of a platform thread. Instead of interfacing this properly, a raw store was used. But a future GC algorithm, such as generational ZGC, might not work well with raw stores. We should add support to the access API for this.
