The CLC response synchronization only involves shared memory (written by UGETNEXTWORKID.BROADCAST, read via LDS). Since shared memory is not cached in L1, the acquire semantics (which insert CCTL.IVALL for L1 invalidation) are unnecessary. Switch to relaxed.cluster to match nvjet's pattern and eliminate ~2.1M CCTL instructions from the hot loop.
