+    target/i386: execute multiple REP/REPZ iterations without leaving TB
+    
+    Use a TCG loop so that it is not necessary to go through the setup steps
+    of REP and through the I/O check on every iteration.  Interestingly, this
+    is not a particularly effective optimization on its own, though it avoids
+    the cost of correct RF emulation that was added in the previous patch.
+    The main benefit lies in allowing the hoisting of loop invariants outside
+    the loop, which will happen separately.
+    
+    The loop exits when the low 16 bits of CX/ECX/RCX are zero (so generally
+    speaking the string operation runs in 65536 iteration batches) to give
+    the main loop an opportunity to pick up interrupts.
