More branch predictor cleanup.
Found small bug. The decode stage was using the predicted instruction class rather than the decoded instruction class.

Reverted to naming IFUStallD to IFUStallF and LSUStallW to LSUStallM. These are generated in the F and M stage.
Generate WFIStallM in the privileged unit rather than generate in hazard.
