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!

also updates to match new gdb output format

- move parsed instructions out of git, to /courses/e190ax/busybear_boot

aren't implemented yet
