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

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

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

Also I'm a bit sketpical this is all working properly, and that no new bugs
