This PR ports the field-logging barrier and related side metadata from the lxr branch.

We also renamed LOG_BIT to OBJECT_UNLOG_BIT to be more consistent and
unambiguous.

Is this outdated now that simplified lxr is merged?

Yeah. LXR introduced field barrier. I think @wks may turn this into a refactoring PR to clean up the field barrier impl, or he may open a new PR for refactoring. I am not sure.
