Local labels in the JIT_ByRefWriteBarrier were not wrapped in the LOCAL_LABEL macro. That causes incorrect unwinding in case an access violation occurs inside of this function. The closest label before the failure point is considered to be the actual function, but it obviously doesn't have the right unwind info. Close dotnet#89585

The closest label before the failure point is considered to be the actual function, but it obviously doesn't have the right unwind info.I have modified all local labels in the same .S file that way.
