Assuming we want to use major opcode 22 for bitmanip instructions for
now, we'll need to decide what to do with the SV ops that are taking
up that space, currently we have:
I propose we reassign them to fit in the mode field of ternary:
0b10001 svshape/svremap/svstep determined by using bits 21..25
This leaves space for the other encodings:
Should I just do that in the csvs or are there other places that need
to be simultaneously updated?
