  73  * Slot 1 store with slot 0 load
  74  * A slot 1 store operation with a slot 0 load operation can appear in a packet.
  75  * The packet attribute :mem_noshuf inhibits the instruction reordering that
  76  * would otherwise be done by the assembler. For example:
  77  *     {
  78  *         memw(R5) = R2 // slot 1 store
  79  *         R3 = memh(R6) // slot 0 load
  80  *     }:mem_noshuf
  81  * Unlike most packetized operations, these memory operations are not executed
  82  * in parallel (Section 3.3.1). Instead, the store instruction in Slot 1
  83  * effectively executes first, followed by the load instruction in Slot 0. If
  84  * the addresses of the two operations are overlapping, the load will receive
  85  * the newly stored data. This feature is supported in processor versions
  86  * V65 or greater.
  87  *
  88  *
  89  * For qemu, we look for a load in slot 0 when there is  a store in slot 1
  90  * in the same packet.  When we see this, we call a helper that merges the
  91  * bytes from the store buffer with the value loaded from memory.
