Wrap access to object's metadata in external functions with
metadata_access_enable()/metadata_access_disable() function calls.
This hooks separates payload accesses from metadata accesses
which might be useful for different checkers (e.g. KASan).

Wrap access to object's metadata in external functions with
metadata_access_enable()/metadata_access_disable() function calls.
This hooks separates payload accesses from metadata accesses
which might be useful for different checkers (e.g. KASan).
