busybear: allow testbench to ignore lack of MMU for now
...
I'd really like to go over this with someone else, not sure if this is
a good thing to be doing
If it is, we're at 1M instructions!

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
