Both root verification and object oop field verification applies load barriers before oops are verified.
The removal of IN_CONCURRENT_ROOT introduced a load barrier to our root verification, which is unnecessary in the Mark End pause, where all roots should be good. This should be changed to a RawAccess.
The object oop field applied a load barrier to be able to verify the Reference referent objects. The proposal is to skip verifying the referents and use RawAccess to verify all other fields.
