9274d09ae2 busybear: better instrF checking
So this now checks instrF only when StallD is low. @kaveh I'd love your
opinion on this. I don't know if this is a good idea or not. Ideally we
should probably be checking InstrRawD instead, but I kind of want to stay
checking the instr in the F stage instead of D for now. Idk if this is worth
staying in F, I can't really see any big downsides to checking the instruction in
D except that PCD isn't an external signal, but neither is StallD, so.....
Anyway I'd love others' thoughts on this
