Annotate the remaining x86 instructions with SchedRW lists.

Browse Source 
Now all x86 instructions that have itinerary classes also have SchedRW
lists. This is required before the new scheduling models can be used.

There are still unannotated instructions remaining, but they don't have
itinerary classes either.
