Nice to see us moving away from compiler intrinsics, embracing C++ 11 features. As per making sure this works with MSVC, I won't burden you with making sure this works right now. Once it's merged (hopefully soon :) ) I'll see if this all builds, and we'll go from there.

Was looking through and noticed some style inconsistencies in one file. Just some drive by comments.

Can you change this auto to be an 'auto *' since it is a pointer?

auto side = oldbits.getSideTable();
side->incrementStrong(n);
}

Why is the else here on another line? (I am asking since below you are writing '} else {'.

Is there a reason the ! has a space after it?

Hi, any progress on this one? It's blocking the Windows (at least with MSVC, the default configuration) build

We're waiting on an LLDB change so the debugger can read weak variables correctly after this change. That is supposed to happen soon but debugger engineer hours are a scarce resource.
