Hello.
I’ve changed the previous patch. `group` field in LWLock is removed, so the size of LWLock will not increase.
Instead of the `group` field I've created new tranches for LWLocks from MainLWLocksArray. This allowed to remove a loop
from the previous version of the patch.
Now the names for LWLocks that are not individual is obtained from corresponding tranches.
