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

e89af96bc0 busybear: more updates 
now gets to instruction 839037 before failing
also updates to match new gdb output format

umm there seems to be something wrong with the SSTATUS CSR. Just leaving
it out for now, will come back and check it later

01b1b1705d Busybear: next week of updates 
- move parsed instructions out of git, to /courses/e190ax/busybear_boot
 - parsed first 1M instructions, and now parse from split GDB runs
 - now at about 230k instructions, can't progress further for now since atomic instructions
   aren't implemented yet

f1768ee50b Busybear: start checking CSRs 
scounteren and mcounteren are currenly manually deleted from the CSRs list
(see slack channl #linux-bringup)

and 3 of the CSRs referenced are skipped because of weird locations for them

oh and this doesn't check their initial state, just their changing. This could be a problem

cca60ed06d update busybear testbench to conform to new structure 
aaaaaaaaaaaaaaaaaahhhh so many changes

also the testbench now uses another internal signal,
which I don't like, but I can't think of a better option rn
