We are not providing the required single-copy atomic semantics for the 64-bit operation that is the 32-bit paired load. At the same time, leave the entire 64-bit value in cpu_exclusive_val and stop writing to cpu_exclusive_high. This means that we do not have to re-assemble the 64-bit quantity when it comes time to store. At the same time, drop a redundant temporary and perform all loads directly into the cpu_exclusive_* globals.
