rv32ic and busybear still have issues.

Improve version of the function radix which does not cause the wave file rendering to slow down.

Function radix slows the simulation by 70 to 76 s (8.5%) for the rv64i tests.

Finally I think I have the function radix mapping across all applications correctly. I still need to clean up the code a bit so it is easier to understand.

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

Shreya and I found a bug with the exeuction of JAL and JALR instructions. The link was only set in the writeback stage. Once the branch predictor started correctly predicting JAL(R)s the ALU and forwarding logic need to have the PCLinkE at the execution stage in case an instruction in the next two clocks need the data.
