Add partial Sv48/Sv57 support

to change.

separate btb response mask from the frontend mask
...
It is now the job of the pipeline to monitor the frontend's valid mask (of
instructions) and the BTB's suggested valid mask (based on the prediction it
makes). Some processors may want to ignore or override the BTB's prediction and
thus can supply their own instruction mask.
