[X86] Update folding table generator to properly detect RMW arithmetic instructions.

The RMW instructions are detected by reading the SchedRW data, but the RMW instructions have had their SchedRW changed in recent months. This broke the expectation.

We probably should fix this to use the mayLoad/mayStore flags if possible.
