Quick: Fix LVN/GVN handling of acquire operations.

Acquire operations, i.e. MONITOR_ENTER and volatile GETs,
change the thread's view of the memory, so subsequent loads
must get new value names in LVN/GVN. Release operations do
not affect this thread's view of the memory, they the only
push the modifications for other threads to see.
