crashing, but I won't bother digging further.

bugfix in mandelbrot-fixed
...
Thanks to comparing regular ints with fixed-point ints, I was computing
iterations for many screenfuls of pixels to the right of the current one.
(Y-axis behaved similarly, but there it was just doing other work instead
of busy-looping forever. If you don't have anything else to do, it doesn't
matter what you do.)

Basically this should never, ever happen until I start reclaiming heap
memory. I believe the only reason it happens is unprotected writes to address
0 or thereabouts.

starting to implement first macros

Another commit, another bugfix.
Some snippets from my currently exploding todo list:
- always investigate lookup errors immediately. Beyond the root cause, they should never happen at the moment, while we aren't reclaiming memory.
we should always return a more precise error message. Usually involving null pointer checks.
- on abort, print out stack trace
- emit mapping of labels to addresses during survey
- store a mapping of symbols somewhere in the code image
- stop allocating 1KB per token; expand space for tokens as needed

In the process I spent a long time tracking down a stray TODO in 108write.subx
that I thought would abort but didn't since the switch to baremetal.
Then after I reintroduced that assertion I had to go track down a bunch
of buffer sizes. Stream sizes continue to be a huge mess.
